Description: This system is one automated switchboard with main ACB breakers that every transfer needs and has a S7-200 PLC plus a WinCC Flexible surveillance system connected to the PLC via profibus. In case that one transformer fails, an instruction is given so that the substitute can take over its circuits. In case something happens and the substitute also fails, an instruction is given to close the coupler breaker in order to feed the power circuits from the generator. This system gives us the opportunity to choose between main, substitute and third transformer, as well as total information in case of an error.
