Contractors are increasingly being tasked with installing fiber optic cables for datacom applications. ‘Running’ or ‘pulling’ fiber has similar challenges as copper and other communications cables, but also has its own particular requirements. And, when finally installed, the next step is to qualify the fiber optic link to ensure that all customer design parameters have been met.

Growing appetite in Saskatchewan for stolen copper SaskPower (saskpower.com) says stolen copper is a problem that has become progressively worse in recent years as it continues to see cases of theft from its substations and other facilities. Sean McKim, director of Enterprise Security at SaskPower, noted the “thieves are placing themselves and SaskPower employees at serious risk”. The utility is working to replace existing copper parts in its electrical equipment with alternatives. Increased monitoring and a stronger security presence are also underway, says the utility. Visit tinyurl.com/o2v8kzf for a video on grounding copper theft in Saskatchewan. Students on The Rock are HotShots at energy conservation Four classes of students in Newfoundland & Labrador were rewarded for their energy conservation knowledge and creativity by being named grand prize winners of the K-I-C Start energy conservation contest for grades kindergarten through 6. Designed to raise awareness about the importance of energy conservation, the contest is one of several components offered through the provincial government’s HotShots initiative and the TakeCharge school program. Students were invited to submit projects that demonstrate the importance of energy conservation. Over 30 submissions were received, including videos, posters, magazines and songs. Visit tinyurl.com/p2tedzh for a video showcasing the work. IESO reports strong results for Ontario energy savings Preliminary results indicate Ontario scored strong energy conservation results in 2014, said the province’s Independent Electricity System Operator (IESO). The results show that local distribution companies (LDCs) across Ontario achieved 98% (5882 GWh) of cumulative energy savings, against their energy-savings target set by the Ontario Energy Board of 6000 GWh for the 2011-2014 period. IESO (www.ieso. ca) said it expects this target to be surpassed when the verified results come in. Yukon Hospital re-signs with renewable power program The Yukon Hospital Corp. (yukonhospitals. ca) has rejoined a program that allows it to use renewable power to heat Whitehorse General Hospital instead of fossil fuels. Yukon Energy’s (www.yukonenergy.ca) secondary sales program prices the renewable power at a discount compared to heating oil. This saves companies about 30% on their heating bills and cuts down on greenhouse gas emissions, Yukon Energy stated. Hydro One invests over $845 million for electricity reliability Hydro One (www.hydroone.com) says it completed more than $157 million in upgrades through 10 transmission station projects across Toronto and the GTA in 2014 to improve reliability and replace aging infrastructure. It plans to invest over $688 million in additional work between 2015-2018.

Through its asset analytics tool, Hydro One said it is able to identify and monitor the condition of all of its critical assets and make more effective investment decisions. Replacing critical assets as they approach end of life is key in ensuring reliability, Hydro One added. New additions to the IEEE 3000 Standards Collection IEEE (www.ieee.org) has approved four new standards in the IEEE 3000 Standards Collection for Industrial and Commercial Power Systems (formerly IEEE Color Books), which sets guidelines and establishes standards for power generation and distribution. The new standards were created to support power-oriented engineers responsible for electrical design and safety. They are: IEEE 3001.5, IEEE 3003.2, IEEE 3004.5 and IEEE 3006.5.

Industry documents & events go hand-in-hand

L

ast month, I conducted a one-hour overview of the 2015 edition of CSA Z462 “Workplace electrical safety” at the latest Sarnia-Lambton Electrical Safety Forum (SLESF). Facilitated by Ontario’s Electrical Safety Authority (ESA), this one-day forum continues to help improve electrical safe work practices in the area. The event also featured Scott Saint, ESA’s chief public safety officer, a Q&A session from SLESF’s Working Live Subcommittee, a working live session facilitated by the Ministry of Labour, a session on Ontario Electrical Safety Report’s (OESR) by Dr. Joel Moody, and more. But this is just one of many electrical safety knowledge events being conducted all across our country, in many different locations, all of which contribute to the downward trending of electrical injuries and fatalities in Canada. It was evident from ESA’s latest OESR that statistics in the United States are following a similar downward trend, and while this is good news, we are still not where we need to be. We can do better, and that’s where Z462 comes into play. In early April, I travelled to Regina for a meeting of the Z462 Technical Committee (TC). The scope of this two-day meeting was to prepare Public Inputs for the July 6 deadline to the NFPA 70E “Standard for electrical safety in the workplace” process in the States. (We work with our American counterparts for the betterment of both nations’ workplace electrical safety documents. CSA has approved Z462 for another three-year cycle, so the next edition will be published in January 2018. This keeps us in step with both the CE Code’s and NFPA 70E’s three-year cycles.) In Regina, we first addressed reports

Untitled-5 1

from the standing NFPA Harmonization and Communications subcommittees. As standard procedure at the beginning of any new document cycle, we confirmed the Technical Committee’s structure and the re-establishment of any required working groups. (Subcommittees are never removed, as they are a normal part of the process.) As a result, the following working groups have been re-established for the 2018 edition of CSA Z462: • WG 2: • WG 3: • WG 4: • WG 5: • WG 6: • WG 7: • • • • •

WG 8: WG 9: WG 13: WG 14: WG 15:

The Z462 TC has been working on, and preparing for, the 2018 edition for the last two years. Based on the work of the subcommittees and working groups, Public Inputs to NFPA 70E’s Technical Committee are the first step toward possible changes to CSA Z462-18. Of course, changes to Z462 can and will be made as required to suit the Canadian workplace.

The CSA process requires that consensus be achieved within the Technical Committee before any changes can be implemented and, because the TC is balanced by a matrix structure, no single interest can dominate the outcomes. Consensus always rules. There are currently 32 voting members (along with their alternates) on the Z462 Technical Committee. The next meeting of the full TC will be held February 17-18, 2016, at CSA Group’s offices. The subcommittees and working groups will carry on with their preparation work by email, teleconference and face-to-face meetings, as required. (And, with the exception of the very last TC meeting in a cycle, guests are welcome to attend this meeting, but only when approved before-hand by the chair and CSA program manager.) A lot of work (done by a lot of people!) goes into producing a document like CSA Z462, which really comes to life when you’ve had it explained and discussed at an industry event like the one I mentioned above, or a host of others across Canada. Only when you engage with Z462 alongside your peers and subject matter experts can you achieve a truly deep understanding of the knowledge contained therein. A subject-matter expert on electrical safety, Mike Doherty is the director of learning & continual improvement at Shermco Industries Canada Inc. He is a licensed electrician and an IEEE senior member, and has served as the Technical Committee chair for CSA Z462 since its inception. His specialties include electrical safety and health & safety management, maintenance, consulting, training, auditing and electrical incident investigations.

lectrical contractors are increasingly being tasked with installing fiber optic cables for datacom applications. ‘Running’ or ‘pulling’ fiber has similar challenges as copper and other communications cables, but also has its own particular requirements. When the fiber cable is finally installed, the next step is to qualify the fiber optic link to ensure that all customer design parameters have been met. This article will discuss the installation, qualification, reporting and subsequent troubleshooting and repair of typical fiber optic links. The nuances of fiber cable Fiber optic cable has many advantages over copper transmission cables, such as: • Highest bandwidth-density product • Small size and light weight • EMI/RFI isolation (SCADA [supervisory control & data acquisition]) • Intrusion resistant (water) • Immunity to electrical shorts • Wide temperature range • No spark or fire hazard Fiber cable also comes with some additional safety requirements. You should never look directly into a fiber cable, bulkhead or the bulkhead of any instrument. The light emitted from these instruments and cables is infrared and invisible to the human eye, but can be damaging. Protective

infrared eyewear should be worn when working with potentially live fibers. Also, the fiber end cuts produced during fusion splicing and termination can embed themselves into your hand or eyes, so protective eyewear should be worn. Fiber end cuts should be disposed of in a suitable container. Most datacom links are point-to-point (P2P) type of networks, which are characterized by a source and a receiver. This can be a simplex or duplex type of fiber. Simplex allows for one-way data transmission while duplex systems provide two-way. Fiber-to-the-X (FTTx, with ‘x’ representing home, curb, business, etc.) is another popular type of network. FTTx networks have bi-directional data transmission, and typically transmit data and video services through a splitter topology. Fiber optic cable installation Fiber optic drop cables have traditionally been hand-pulled due to their short lengths (50 ft to 500 ft, but averaging 200 ft). These cables may be round, flat, armoured or dielectric. Although distances for fiber drops are typically short, the distance in business parks and rural settings may at times exceed 500 ft and up to 1200 ft. The traditional method for installing fiber drops has been ‘hand-pulling’ but, with the frequency of installs increasing due to consumer demand, there is an emphasis on worker and fiber cable safety. Hand-pulling potentially leads to wrist, arm and shoulder injury. Standard

cable-pulling machines, however, tend to be heavy, difficult to transport from residence to residence, expensive, and require too much set-up time. Fiber-blowing technology is being implemented for round or flat drop cables with outer diameters of 3.0 mm to 10.5 mm, where the fiber is pushed through the micro-ducts. Longer distances can be accommodated with compressed air (jetted) and lubricants. Fiber counts from 1 to 144F microcables may be pushed or jetted. It is also possible to blow fiber into larger outside plant (OSP) ducts from 1/2-in., 3/4-in., 1-in. and 1 1/4-in. i.d. (inside diameter) using cabling speeds from 25 fpm to 300 fpm (feet per minute). Fiber-blowing reduces the dangerous aspect of fiber pulling and paves the way for efficient fiber installations. Some fiber optic cables are pre-terminated in the factory and ready for qualification and turning up of services once installed. This is very convenient, and the connectors are of very good quality since the terminations were made in the factory. The disadvantage is that the exact length fiber is probably not available, and the excess fiber must be safely installed and protected from damage. The other disadvantage is that the connector must be handled carefully, and might be damaged during fiber installation. When the fiber is not pre-terminated, the ends—naturally—will need to be terminated. This can be done with splice-on connectors (SOCs) or mechanical connectors, or by splicing half of a patch cord to the end of the fiber.


Fusion splicers are used to splice two fiber optic cables together, with some splicers capable of splicing a fiber optic cable to a splice-on connector. The use of SOCs in a fiber optic installation provides many advantages over mechanical connectors, and the method of splicing patch cords cut in half onto fiber optic cables (field fiber). Typically, SOCs are lower in cost when compared to mechanical connectors. The SOC is also precleaved and ready for splicing to the field fiber, thereby eliminating the time-consuming fiber stripping and cleaving processes. The need for splice trays is also eliminated, since the splice protector is housed within the actual SOC strain-relief boot. Fiber installations are also much neater and easier to manage because you do not need to estimate the length of the field fiber and patch cord, so the resulting splice protector can be mounted into a splice tray. Splice-on connectors do not add any additional loss to the overall connector, since fusion splicing has virtually zero loss, whereas a mechanical connector could add up to 0.4dB to the total loss for each connector. The SOC can be used in outdoor installations and is not affected by temperature variations and mechanical vibrations. When a mechanical connector is subjected to temperature or mechanical stresses, the insertion and return loss could increase substantially. This is caused by the fiber cleaves coming apart or shifting and/or the index matching gel shifting or drying up. Therefore, the overall loss budget and bit error rate would be compromised with mechanical connectors. The fiber end face of SOCs is factory-polished and outperforms field-polished connector products. When a mechanical connector does become lossy, you would have to first troubleshoot then repair the offending connector. This can, in fact, become one of the greatest cost savings with SOCs, since they would not have such a failure and would save expensive truck rolls. Fusion splicers can output the splice history so that a ‘birth certificate’ for each fiber splice can be generated to prove the quality of the splice with a time stamp and all other data specific to that splice.

which can be either a fully automated OLTS (automatically measures the insertion and return losses in both directions); another method is to use an individual laser (or LED) source with a complimentary optical power meter (OPM). Both of these loss test methods will not pinpoint where the losses are, as they only give the cumulative loss of the entire link. Optical

time domain reflectometers, on the other hand, are able to measure the entire length of the fiber link so that the insertion loss and return loss of every event, and the cumulative losses, are documented. Once the measurements are made with either an OLTS or OTDR, you can generate a report (birth certificate) for the customer as proof of installation and compliance to design specs.

Inevitably, you will have either a problem qualifying or turning up a fiber optic link, or may be called upon to troubleshoot a previously functional link. Testing and troubleshooting tools will be required, and you will need to be well-versed on these tools to be able to effectively locate the fault and get the fiber link functioning again.

produce erroneous results that may send you on a wild goose chase (but you can fiddle with the OTDR to obtain optimum results). First, the overall expected length should be known from documentation recorded at the time of installation. Key settings for the OTDR are the Range, Pulse Width and Averaging Time. The range setting can then be set to the range that is just longer than the expected cable length. The pulse width will then be automatically set for optimum performance. You do have the option of setting the pulse width. A wider pulse width will inject more light energy into the fiber and allow the OTDR to measure longer cables, but the resolution of the measurement will be decreased. A smaller pulse width will yield a result with better resolution but, since less light energy was launched into the fiber, the maximum measurement distance will reduced. Increasing the averaging time will improve the signal-to-noise ratio, which will compensate for long cables being measured and for smaller pulse widths being used.

The time is nigh to electrify... your fleet! Charlotte Argue

E

lectric vehicles have emerged from the garages of gearheads and landed in the nation’s auto malls. And while their numbers aren’t yet threatening the gasmobile, the early adopters snapping up EVs have proven the cars a practical choice for many. While pure electric vehicles are not quite perfect for everyone on the road, those people who have gotten out there and made the switch are reaping the reward, such as the $3000+ per year that an individual driver saves in fuel and maintenance costs.

The case for fleet electrification Commercial and private fleets are particularly well-positioned to take advantage of the switch. Fleet drivers often follow regular routes, with a set schedule and a central dispatch... all ideal conditions, it turns out, for battery power. There are financial benefits, too; over the seven-year life of each fleet vehicle, operators could save $10,000 or more, despite the higher upfront price tag. In addition to a substantial decrease in fuel costs (up to 1/8th the cost per kilometre driven), electric cars require less maintenance, no oil changes and have less brake wear and tear. Fleet managers will also enjoy predictable, static electricity prices relative to daily changes in gas or diesel prices. Of course, not every fleet is ready for an extension cord. An electric 18-wheeler, for example, has yet to hit the market. That said, a study by FleetCarma found that 90% of the vehicles in the fleets they assessed were EV-ready. In July 2014, fleet managers in Oregon gathered for a workshop to identify where electric vehicles

would have the greatest benefit. They flagged predictable routes; short, regular trips; quiet, no-idling operations; and high-use vehicles. The City of Vancouver, meantime, is a local success story. Last year, electrics met 16% of the city’s new-vehicle needs. City councillor Raymond Louie has said they are ideal for the commutes of city staff, and there is an emerging business case for the cost savings.

emotive: promoting the Ev experience In an effort to raise public awareness of electric vehicles, the Province of British columbia—along with the Fraser Basin council, Metro Vancouver, city of Vancouver and city of Surrey—collaborated with a PR firm to launch a public outreach campaign called “emotive: the electric vehicle experience”. the group applied existing market research to identify target audiences and define key messaging to raise the profile of EVs. the campaign concept capitalized on the fun and exciting feeling of driving electric cars. key findings of the market research were presented at Electric Mobility canada’s 2014 annual conference (emc-mec.ca). Attendees learned about the strategy’s development and execution, any successes and challenges, and how outreach efforts were being amplified through community partners and EV ambassadors across the province.

Ev battery owning/leasing & enhanced charging

1) 2)

Range Anxiety: the concern that the driving range of EVs (typically 80 miles given current battery capacity) isn’t enough to meet a driver’s needs. Resale Anxiety: the concern that the price of used EVs will not hold strong in the future, making it difficult for owners to resell their cars.

to understand the impact of consumer anxieties, the authors used a two-stage, game-theoretic modelling framework. the first stage examines the ”introduction phase” in which only new EVs are available. At this stage, consumers have little experience with the product and exhibit both types of anxieties. the second stage is the “maturity phase” in which both new and used EVs are available in the market. At this stage, the authors consider anxieties to diminish as consumers learn more about electric vehicles and the market. calibrating the model to the San Francisco Bay area freeway network, auto market figures and industry reports, the authors examined several business options to determine which would reassure consumers while also yielding desired profits. In contrast to the common current American model for EVs in which consumers own the vehicle with battery and recharge it at home overnight, the authors found two models offering promising alternatives. the first model represents the case in which an enhanced battery-charging service is made available through additional support infrastructure. this includes, for example, tesla’s supercharger stations and other quick-charging stations that are being introduced in the U.S. by firms such as chargepoint and NRG eVgo. In the second model, consumers lease the batteries and are also offered enhanced battery-charging services. one example is a business model that offers enhanced charging in the form of battery swapping coupled with the battery leasing service. In a second example, Renault is selling its ZoE in Europe with battery leasing and the support of quick-charging infrastructure. Interestingly, increasing the driving range of EVs through greater public charging infrastructure typically yields more “socially desirable adoption outcomes” (greater adoption and emission savings) than increasing the battery capacity of the EV itself. “therefore,” the authors advise, “policymakers must take into account these factors in implementing governmental policies to properly incentivize the involved parties, especially the private sector.”

A proper choice of business model plays a critical role in the electric vehicle industry where consumers are subject to range and resale anxieties. In particular, a combination of owning or leasing electric batteries and improving charging technology can reassure skeptics and help increase EV adoption. this is the finding of a study published in a paper entitled “toward Mass Adoption of Electric Vehicles: Impact of the Range and Resale Anxieties” by Michael k. Lim of the University of Illinois at Urbana-champaign, ho-Yin Mak of hong kong University of Science & technology, and Ying Rong of Shanghai Jiao tong University. According to the authors, two psychological barriers are holding back an increase in EV purchases:

While not quite all-electric, the onboard generator in this via Motors’ work truck can provide a worksite with 14.4kW of exportable power. Despite proven successes and the business case for cost savings, barriers to adoption linger for many fleet managers. The upfront cost, range anxiety, lack of familiarity, and the limited number of models from which to choose remain very real concerns. Bit by bit, these barriers are coming down. As the market grows, vehicle costs continue to fall. The price of batteries—an EV’s mostexpensive component—has fallen by 50% in the last four years, and Bloomberg New Energy Finance expects prices will halve again in the early 2020s. As a cushion, many governments are offering rebates until we hit that sweet spot. Ontario offers consumers $5000 to $8500, depending on the size of the battery pack. Similarly, Quebec’s rebate ranges from $5000 to $8000. Boosted by incentives and lower battery costs, automakers are introducing new battery electric and plug-in hybrid vehicle models every year. Soon, full-size SUVs, pickup trucks and vans already available in other markets will come to Canada. Governments lend a hand Fleet managers interested in integrating EVs now have access to a wider range of resources and support. Just over a year ago, the British Columbia government (along with California, Oregon and Washington) committed to pursuing a goal whereby 10% of all new vehicles purchased for public or private fleets must be zero-emission by 2016. The goal might sound modest to some but, if realized, has potential to make a big impact. It would mean that, by next year, one in 10 vehicles purchased by provincial or local government—or companies operating in those jurisdictions—will emit no carbon pollution whatsoever. This would add about another 3000 EVs beyond the 1166 already roaming the Pacific Province. We may soon be seeing electric vehicles everywhere, from taxis and delivery vans to carshares. The Pacific Coast Collaborative—the partnership of West Coast governments

overseeing the 10% fleet target—developed a toolkit that helps organizations see how well electric vehicles would fit for them. It includes cost calculators, vehicle incentives, and resources on available fleet vehicles (tinyurl.com/opumk5g). To facilitate the next step, Clean Energy Canada and the Fraser Basin Council— in collaboration with Electric Mobility Canada—presented “Electrify Your Fleet” in Vancouver at EMC’s EV2014 national conference (emc-mec.ca). Experts were on-hand for those keen on diving into the details of having electric vehicles in their fleets. Speakers dissected barriers to EV procurement, as well as the environmental and financial benefits of integrating zeroemission cars into existing fleets. The Pacific Coast Collaborative has taken the lead with its 10% target. Now it’s up to the rest of us to pick up the ball and run with it, and reap the benefits EVs can bring. With falling costs and a wealth of resources available, now is the time for fleet managers to seriously consider adopting electric vehicles. Submitted by Charlotte Argue, this article (co-authored by Fraser Basin Council and Clean Energy Canada) ties in with a presentation she delivered on behalf of Plug In BC entitled “Emotive: Promoting the Electric Vehicle Experience” at Electric Mobility Canada’s 2014 annual conference (see sidebar page 12).

Speaking of tools, if you bought new ones for work this year, you may have been able to claim a tradesperson’s tools deduction of up to $500 on your tax return. You may also have been eligible for a GST/HST rebate. If you’re self-employed, you may have been able to deduct other reasonable expenses you paid to earn income, including vehicle expenses, supplies needed to complete a job and office space expenses. Have you converted part of your garage into a workspace for building custom cabinets? When you use part of your home for business, you can deduct a portion of your maintenance costs such as heat, home insurance, electricity, cleaning materials and more. To find out more, visit www.cra.gc.ca/smallbusiness and select Business Expenses. Don’t forget that the deadline to file your income tax and benefit return is generally April 30. However, if you or your spouse or commonlaw partner is self-employed, the deadline is June 15. But take note: if you have a balance owing for 2014, you still have to pay it on or before April 30, 2015. Employers can benefit too! If your business hires a qualified apprentice working in an approved Red Seal trade, you may qualify to claim the apprenticeship job creation tax credit. This non-refundable investment tax credit is equal to the lesser of $2000 or 10% of the eligible apprentices’ salaries or wages. Don’t need to use the whole credit amount this year? Carry the unused amount back three years or carry it forward up to 20 years! For more

And beware the underground economy your clients suggest you do a job under-the-table, understand that you are putting yourself at risk by accepting cash and avoiding taxes. If you are caught evading taxes, you may face fines, penalties or even jail time. Save yourself the trouble—don’t participate in the underground economy. Under-the-table deals undermine the integrity of Canada’s tax system, and provide certain contractors with an unfair, illegal advantage over those who follow Canada’s tax laws.

We continue to explore electrical technologies, products and systems for the discerning homeowner... where cost is not an issue! This month we look at the latest and greatest in signalling systems—specifically, intercom and home security platforms that take monitoring above and beyond your client’s perimeter.

Gamify the home with luxury security Renée Francoeur

trolling through the labs and teeming testing rooms at Mircom’s corporate headquarters in Vaughan, Ont., it doesn’t take you long to see how far home security systems have come. Gone are the bulky, steel boxes of numbered buttons and separate control systems for fire alarms and door locks. Today, it’s all about a sleek touchscreen. “Security goes beyond the perimeter of the home now,” said Jason Falbo, Mircom’s vicepresident of engineering. What he means is that smartphones and tablets are able to track both the property and the occupants themselves via a motley of sensors that transmit information in real-time 24/7. In other words, a client’s interest in a mere gate camera can be just the beginning. Mircom’s TX3 InSuite platform package can start with a basic video doorbell and expand to integrate room-to-room video intercom, home automation and system integration. The TX3 station comes with a 10-in. LCD tablet that acts as the main controller. It answers calls, records and greets visitors outside, and integrates with access control to lock doors. It can also be programmed to control lights and appliances, and share announcements and calendars with the home’s occupants. Another bonus with the tablet technology is the ability to relay and capture monitoring information remotely from any smartphone via a web portal. For a single-family house of about 2000 sf to 3000 sf, packages can be as low as $3000 to $5000, Falbo said. In the luxury market, that figure can climb upward of $100,000 for total automation and beyond. Speaking of beyond, very high-end systems may come with the ability to instruct a faucet when to run a bath, or tie into a wearable device that monitors an aging parent’s blood pressure, Falbo added. Mircom’s systems are power-over-ethernet (PoE), leveraging the IP network—a benefit for contractors because the infrastructure is already there, Falbo explained. At Leviton Canada, the ultimate home would have to be fitted with an OmniPro II

automation system, including all OmniTouch 7 products, according to Maurice Bouskéla, business development specialist with Leviton’s security and automation department. Installing an Omni system can cost around $3/sf to $4/sf inside a home and upward of $7/sf as you add “all the bells and whistles,” Bouskéla said, such as home theatre controls. Bouskéla also pointed out they are seeing an increased demand for BitWise controllers. Small, black boxes that can be put anywhere, these “mini processors/IP-based communicators” use a tablet or smartphone interface to control sub-systems. For example, after arming the Omni system, the BitWise will send out infrareds or RS232 commands to turn off a TV that had been left on. When it comes to security systems, flexibility is key for ELK, a manufacturer of home convenience solutions based in North Carolina. With ELK’s M1 Gold hybrid (hardwired and wireless) control system (with a built-in astronomical clock), clients can program their own rules. It has 16 on-board zones, expandable to 208. “Let’s say when a client opens a front door, they want the foyer light to come on... but only when it’s dark outside. Well, they can write this custom rule from drop-down menus,” said Trudy Phillips, ELK’s director of sales and marketing. Start-up kits for installers start around $500 US.

Additionally, the two-way wireless technology is practically “hacker-proof,” Phillips claimed. “It scans and hops across 25 frequency channels making it virtually impossible for an outsider to scan or lock onto the operating frequency,” she said, adding it has the UL listing that requires it to detect and report outside jamming. As for how to market such dream homeworthy products to clients, Falbo recommended that contractors demonstrate the return on investment. “You see a return quite quickly, whether it’s with reduced electrical consumption or otherwise,” he said. “Some basic financial spreadsheets can be used to show people how great these solutions are.” Blogging about these installations and citing case studies is also valuable, he said, because “people buy based on a feeling that it’s established and someone else is using it”. With these types of updated systems, another selling point is the fact that clients don’t have to deal with multiple companies or pay a third party, Bouskéla said. Additionally, they’re not as complicated to program as they once were thanks to remote smartphone interfaces. A PoE “one-system-does-all” is also attractive to Generation X and Y buyers who are looking for something new to showcase as a “source of pride,” Falbo said, adding these systems are like “gamifying your life”.

When it comes to high-end homes, there’s no such thing as “too much”. So for those with rooms full of inherited artwork or valuables worth a substantial amount of money, clients may want a separate fire alarm/control system. Mircom’s suppression control units are used primarily in data control centres as well as museums, Falbo said, but it isn’t unheard of to put one in a luxury home where high-value assets deserve protection. “When you have a suppression system with a dry agent or a gas, it will actually go and extinguish a fire to protect painting, clothes,” said Falbo, noting that it may be too late for the valuables inside with standard alarm fire detection systems.

ind energy is one of the fastest-growing sources of electricity around the world. However, wind is an intermittent resource and CO2-emitting fossil fuels like coal are often needed to help balance the power load. A demonstration project at the Cowessess First Nation near Regina, Sask., aims to demonstrate that a combined wind generation and battery storage system can provide constant, continuous and renewable electricity for on-grid applications. The first of its kind in Canada to use lithium-ion batteries for wind energy storage, the project is also generating new revenue for the First Nation through the sale of the electricity to SaskPower, the provincial power utility.

Wind energy and storage technology Given its geography and climatic conditions, Saskatchewan has considerable potential to harness wind energy. These conditions would allow for wind turbines to generate approximately 40% of the province’s electricity annually were that potential to be fully realized. With funding received from Natural Resources Canada (NRCan), a wind-battery storage system was installed in April 2013 on land near Regina owned by the Cowessess First Nation. Consisting of an 800kW turbine and two 200kW lithium-ion batteries, the storage system allows more energy to be captured and used. The combined system is now producing about 2200MWh of electricity per year—enough energy to power 300 typical Saskatchewan homes. “Because wind energy is intermittent, one of the benefits of battery storage technology is that it allows for a more constant flow of electricity,” says Rob Brandon, assistant program director with NRCan’s Office of Energy Research & Development. Battery storage systems provide electricity when needed and store extra energy produced on windy days for use during low-wind periods.

power output from wind by almost 80%. Furthermore, by displacing power from the province’s coal-fired power plants, the system is expected to reduce Saskatchewan’s greenhouse gas emissions by almost 2000 tonnes annually. “Collection of wind energy combined with the ability to store the energy and use it during low-wind situations could significantly increase our future capacity to use wind resources as an alternative to fossil fuels,” says Brandon.

Wind energy and storage potential The project is a collaboration between NRCan, the Cowessess First Nation and the Saskatchewan Research Council. Since its installation in April 2013, the storage system has been able to reduce the volatility of the

Future for wind storage technology Researchers are studying potential future applications for this technology, including the possibility for it to act as a stand-alone unit and provide electricity to remote off-grid communities in Canada and elsewhere. For example, there are 75 First Nation home reserve lands in Saskatchewan, and about 20 of these have excellent sites for potential replication. The project will supply energy to the grid through a 20-year power purchase agreement as part of SaskPower’s Green Options Partners Program. “Harnessing the wind to produce electrical power has the potential to be an excellent business opportunity for First Nations people in Saskatchewan and across Canada,” Brandon noted.

Photovoltaic system rapid shutdown

T

he 2015 CE Code contains several interesting changes and new requirements for solar photovoltaic installations, including a requirement for rapid shutdown. New Rule 64-218 “Photovoltaic system rapid shutdown”—as the name implies—requires a way to quickly and safely de-energize the downstream electrical equipment to address the inherent shock hazard that solar PV systems present to first responders (e.g. firefighters). Interestingly, the new rule does not specify how to execute rapid shutdown—only the end result. Rapid shutdown requirements apply to solar PV systems on buildings and encompass the overall ‘PV system’, which includes the PV source and output conductors, inverter I/O, batteries, and charge controller I/O. These requirements apply to solar PV circuits that are more than 3 metres from a PV array or circuits that extend more than 1.5 metres in length inside a building. Were a combiner box installed within 3 metres of a PV array on a typical roof-mounted PV installation, for example, the PV output circuits and AC circuits must be enabled for rapid shutdown, whereas the PV source conductors (conductors between PV modules and from PV modules to the combiner) are left energized. Rapid shutdown does not actually mandate 0 volts on these circuits. Instead, the Rule requires the voltage be limited to 30V and 240VA within

10 seconds of rapid shutdown initiation. Based on Rule 64-200(2) and (3), a rapid shutdown marking shall be provided at the disconnecting means for the PV output circuit (DG [distributed generator] source disconnect). The marking:

PHOtOVOLtaIC SYSteM eQuIPPeD WItH raPID SHutDOWn shall be in white uppercase letters (minimum height of 9.5 mm) on a red background. Again, Rule 64-218 is not specific as to what can be used as the rapid shutdown initiator, so long as the equipment satisfies the criteria specified. Examples include a utility disconnect switch, DG disconnect switch or rapid shutdown switch. Rule 64-218 also does not specify the location of the rapid shutdown initiator but, considering it is to be used by emergency responders, the most suitable location is typically at or near the service equipment. Let’s consider some examples for satisfying this new requirement. #1. A manufactured rapid shutdown system There are a few such systems in the market and, while some of them provide module-level

• Combiner box with a contactor shall be installed within 3 m of the array. • Control devices and circuitry (that activate a contactor within combiner box) shall be installed to remotely activate the contactor. • Emergency responders are able to initiate rapid shutdown by using either the DG system disconnect, a rapid shutdown controller or utility disconnect switch. #3. Micro-inverters and AC modules These inherently comply with rapid shutdown requirements because of their design and application; all that is needed to achieve a fully compliant installation is to interrupt AC power and provide the marking requirements as per 64-200(2) and (3).
