FIELD: electricity.
SUBSTANCE: power consumption control unit consisting of voltage level setter, current transformer connected to input of rectifier, mode select switch which first output is connected to indicator input while second output is connected to automatic load shedding unit which N outputs are connected to respective tripping inputs of N automatic circuit breakers installed in each electric line feeding a certain group of power consumers. At that the unit includes auxiliary control unit and unit of automatic consumers switching on, which first input is connected to the second output of mode select switch, the second input is connected to (N+1) output of automatic load shedding unit and N outputs are connected to respective switching-on inputs N of automatic circuit breakers; at that the first input of control unit is connected to output of the rectifier, the second input is connected to output of voltage level setter and output of the control unit is connected to input of mode select switch.
EFFECT: improving automatic performance.
