A communication module of a controller for outputting a command relating to an operation and a monitor for auxiliaries to be operated and a communication module of a switch gear for generating information relating to a protection and an interlock for the auxiliaries to be operated are connected through a serial transmission cable wires. Each of the switch gears is connected each other through a serial transmission cable wires. By controlling a CPU in the switch gear, an activation of the auxiliaries to be protected which are connected to a power circuit is commanded and then the protection operation and the interlock operation for the auxiliaries to be operated are carried out. A small scale of the apparatus can be attained and the wiring cables can be lessened.
