31 Aug What is an Automatic Transfer Switch?
An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
Electrical power is provided by the local grid utility company and connected to equipment via electrical distribution boards or panels.
When the primary power source (utility) has ceased to work, power from a generator can be either manually or automatically transferred to the electrical distribution panel via a transfer switch.
A transfer switches’ primary function is to redistribute power from a grid to a backup source of power such as a generator
The control panel system of an automatic transfer switch (ATS) is what makes the unit automatic in nature. An automatic transfer switch detects power failures immediately and the transition from utility power to generator power is instantaneous. The control panel’s function is to detect a power failure and initiate procedures to start the generator’s engine. Once the generator reaches the correct voltage and frequency, the control system signals the switch to transfer from the normal source of power to the generator.
