FIELD: electricity.
SUBSTANCE: device relates to relay protection of power transformer with offset from surge of off-load switching on current. In the device two inertia circuits and diodes with smoothing parallel resistive-capacitive circuit are connected between rectifier bridge with load resistor and responding component.
EFFECT: reliability improvement and device simplification.
