Why We Need The Automatic Transfer Switch?

Is the Automatic Transfer Switch useful for us or it is an option in the backup power system? This question will be answered in this article in details.

Perhaps one of the most important components of your emergency power system, the Automatic Transfer Switch can be the key to your backup power supply. Your generator’s Automatic Transfer Switch is constantly monitoring the flow of power from your regular source, and upon any number of scenarios, will determine the need to switch to your backup generator. A functional generator is useless if its backup power cannot be utilized in an emergency situation.

Uses of Automatic Transfer Switches Automatic Transfer Switches are mostly used to switch between: 1-One generator to another: Systems that use multiple generators as the prime power source.

2-Utility power to generator: These including facilities that have both utility and income power and uses generators for backup only.

3-One utility power to another utility power: Systems operating utility feeds on both ends. These systems can operate with manual switches as well.

4-A three way system including all above: These systems combine two utility sources and one backup generator for sensitive areas like jails and military bases.

These are mostly referred as dual standby systems having two backup and over all three power sources.

Benefits of Using Automatic Transfer Switches There are many benefits of using the Automatic Transfer Switches in backup power system including:

1-Operation: Automatic Transfer Switch includes a network of relays and solid state devices that are installed to monitor and control the incoming voltage. Automatic Transfer Switch acts as a monitor as long as the incoming power is smooth and above a specified level. As soon as the voltage falls it is sensed by Solid State Relay (SSR) devices and generates a signal to start the generator.

2-Isolation: The second duty of the Automatic Transfer Switch is to isolate the grid power from the backup generator. The isolation is provided using opto couplers or solid state relays. The generator remains on and its output is monitored so as to reach a specified level. As soon as that level is reached the switch turns off the utility power and transfers the load to the backup power.

3-Grid power control: The Automatic Transfer Switch continues to observe the grid power that was either completely out or fell below a certain level. If it is back in working mode, the Automatic Transfer Switch turns off the generator and waits for the power to attain a certain level as soon as that level is attained the control is shifted back again and the generator is again held on standby mode. These all things happen very quickly in a matter of micro seconds and the user don’t even feel any voltage variation or spike.

4-Protection: The most important benefit of using the Automatic Transfer Switches is the protection. They must be used whenever transfer of power is needed as they protect your home, your generator, and most importantly the worker.
