automatic transfer switch (ATS)

Description

automatic transfer switch (ATS)are an integral part of the power generation process,allowing smooth and immediate transfer of electrical current between multiple sources and the load.

When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation. The transfer switch senses when utility power is interrupted, and starts up the generator if the utility power remains absent. When the generator is producing full power, the transfer switch disconnects the load from the utility and connects it to the generator, restoring electricity to the load. The transfer switch continues to monitor utility power, and when it is restored, switches the load from the generator back to the utility. Once the generator is disconnected, it goes through a cool-down routine and is automatically shut down.

Zhejiang Yuye Electric Co., Ltd. has several types of transfer switches. Each kind operates in a different way, depending upon the requirements of the overall system, and how the load is transferred between the different power sources. Expertise in the design and manufacture of automatic transfer switches (ATS) is considerable. Open transition transfer switches are the simplest kind, and are mechanically interlocked. They disconnect the from one power source before making the connection to the other.
