MAST MV Paralleling Switchgear

The MAST auto transfer switch system is mainly used in important load networks such as data centers, highways, medical facilities, banking systems,airports, telecommunications semiconductors. In case of mains failure or power failure, the auto transfer switch system can be used to switch to standby power supplies such as Diesel generator power supply to ensure the normal operation of important loads. For the switching process, the lower level loads can be switched, cut off and unloaded step by step.

In case of a mains failure, it can cut off the corresponding load outgoing breaker according to the diesel generator conditions in the preset order; after cutting off the load, it switches off all the mains power circuit breakers, and switches on the reserve power circuit breaker (diesel generator); after the reserve power circuit breaker (diesel generator) is switched, it delays the input of load outgoing breakers according to the preset sequence, to realize the load switching in steps.
