What is Maintenance?

• A regularly scheduled preventative maintenance program is intended to detect, correct, or replace affected components parts or equipment before they lead to a catastrophic failure and significant power interruptions.

• Article 200 of NFPA70E defines maintenance “as preserving or restoring the condition of electrical equipment and installations, or parts of either, for the safety of employees who work where exposed to electrical hazards”

Confidential Property of Schneider Electric

Approaches to Electrical Maintenance

• Reactive Maintenance • Repair work conducted after a failure or breakdown, often completed as an emergency

• Preventive Maintenance • A specified list of inspections, cleaning, testing and part replacement during a pre-defined, time-based schedule

• Predictive Maintenance (or Periodic Diagnosis) • Scheduled based on diagnostic evaluations. Also factors in equipment age, environmental stresses, criticality of equipment etc. to decide on schedule

Confidential Property of Schneider Electric

ARC Advisory Group

Maintenance Plan Development • NFPA 70B states…

• Maintenance requirements vary by equipment class • Frequency should consider criticality, condition and environment • Consider the Manufacturer’s recommendations

• NFPA 70B - Annex L (frequency) • Indoor switchgear • Infrared - annually • Visual - 6 months • Test Insulation - 2 years

• Low voltage air circuit breakers • Inspect/Clean/Adjust - Annually • Test - 3 years

Important Preventive Maintenance Tasks

• Infrared Scanning • Molded-Case Breakers • Should be operated periodically (Keeps contacts clean, helps operating mechanisms move freely)

• MV Breakers • Should be removed from service and inspected at least once per year • Clean, lubrication, exercise • Testing: protective relays, resistance, timing • Bolted Pressure Switches

• LVPCB’s • LVPCB’s not maintained within 5 year period have a 50% failure rate • Cleaning, lubrication, exercise, reconditioning • Testing: primary or secondary current, resistance (current path, insulation)

• Visual inspection and exercising once a year • Cleaning and lubrication should ideally occur annually for current carrying components, but not longer than three years

Types of Predictive Technologies • Power System Assessments • Infrared inspections • Thermal monitoring • Oil analysis • Vibration analysis • Partial discharge monitoring • Circuit Monitor Analysis • Intelligent protective devices – Circuit Breaker electronic trip units – Motor Starter intelligent overloads Confidential Property of Schneider Electric

Predictive Maintenance Solutions Predictive maintenance techniques safely provide condition status to help anticipate and plan maintenance activities.

Infrared Viewing Windows Enhances safety by allowing infrared inspections without the need to remove equipment covers.

Wireless Temperature Monitoring System Allows 24/7 monitoring of critical connection points and areas not seen by infrared cameras.

Partial Discharge Monitoring Detects impending insulation breakdown in MV equipment, which can lead to costly equipment damage and downtime.

Predictive maintenance solutions detect early warning signs and help prevent downtime.

Electrical Distribution Equipment Electrical Distribution Equipment is composed of both Active and Passive Components • Active Components • Circuit Breakers • Trip Units • Relays • PLC’s, TVSS • Fuses • Racking Mechanisms • Monitoring Components

• Passive Components • Structure • Bussing • Lugs/Lug Pads • Bracing Confidential Property of Schneider Electric

Electrical Distribution System Active Components include mechanical or solid state features and many times both • Mechanical Components • Involve moving parts, therefore they must be maintained in order to operate as intended • Will wear out over time • Some components require replacement upon use • Electronic Components • The rise in utilization of solid state components gives rise to another mode of failure that cannot be easily detected • Typically cannot be maintained and must be replaced upon failure • Obsolescence is a key consideration

Electrical Distribution System Passive Components include the non-moving and non-solid state components Structural Components • Require minimal maintenance • If properly cleaned and monitored in a controlled environment, the passive components may last a long time, however: – Dust, dirt and moisture build-up can affect the insulation system – Loose connections due to improper torque and/or vibration over time can lead to excessive heat and failure • If well maintained, these components substantially outlast the life span of the Active Components in a piece of electrical distribution equipment

Electrical Infrastructure Failure Tangible Costs • Equipment replacement costs • Contractor costs • Loss of production • Fines (for spill or backup) • Impact to personnel/medical costs/lawsuits Intangible Costs • Fixed and variable costs wasted during downtime • Possible loss of customer revenue • Internal and external meetings • Human resources allocated to the repair

Direct Replacement or Retrofill?

When considering whether to replace or upgrade existing equipment, there are a number of factors to consider.

•

Operating environment

•

Availability of spare parts

•

Impact of downtime

•

Cost of ongoing maintenance

•

Need to increase fault or continuous current rating

•

Desire to upgrade to current technology

Confidential Property of Schneider Electric Confidential Property of Schneider Electric | | Page 22

Our direct replacement and retrofill solutions modernize any manufacturer’s existing switchgear to current technology.

Direct Replacement or Retrofill?

Our direct replacement and retrofill switchgear modernization solutions will expand the capabilities of your electrical system with minimal downtime.

Direct Replacement

Retrofill

Circuit breakers are designed to fit into the existing cubicle with little-to-no modification to the switchgear cell. Reduces downtime since there is minimal (if any) outage on the equipment bus.

The existing switchgear cell and bus are modified to accept the new circuit breaker. This option requires a longer bus outage (compared to the direct replacement option), during which time the internal circuit breaker cell is modified to accept the new circuit breaker.

A Masterpact cradle-in-cradle design is utilized for LV direct replacement solutions
