How to operate electrical transfer switches

Defining power transfer switch

A power transfer switch is a device that changes the source of power from one to another. Typically it is transferred from a main power source, such as the local company to a secondary power source, such as an emergency generator. The power transfer switch also changes the power to the main power supply from emergency power when it is no longer necessary. The transfer switch keeps the two sources of energy isolated, allowing the safe transfer of a power source to the other.

Operation of electrical transfer switches

Electrical transfer switches often operate automatically, and the power switch is based on power levels just as real shots. They maintain a constant level monitoring the circuit. Automatic can transfer energy without human intervention in the event of any power problem. In the case of a voltage change, as a drop in tension, compression, surge or spike, the circuit breaker will come into action.

Action auto transfer switch

When the automatic transfer switch detects a problem on the primary energy source, will begin the process of starting the emergency generator. Once the generator is running, and determined the correct voltage, the automatic transfer switch will switch the power to the generator. The switch will continue to monitor the primary power source, while the generator supplies the power. Once the primary source of power has been restored, the switch changes the power from the generator to the main power supply.

Types of automatic transfer switches

Alternatively, there are switches that require manual transfer switch so that the power source is switched. These switches are not as technologically advanced, and do not provide a control voltage dips, for example. Finally, using both switches transfer switching automatically or manually. They maintain critical processes in an automatic circuit and are not critical in a manual switch.
