Abstract

PURPOSE: To decrease short-circuit currents while operating a shor-circuit alarm device, by discriminating the short-circuits at the secondary side and the abnormal rise of the voltage at the primary side of this transformer for condenser type meters, and by working a short-circuit protective device only in case of secondary short- circuits.
CONSTITUTION: When there happen secondary short-circuits in a circuit consisting of main condenser C1, a partial-pressure condenser C2, a leakage transformer T, a relay RY for detecting secondary short-circuits, etc., the relay RY acts to give alarms. When voltage at the primary side abnormally rises, the relay RY does not function, and alarms are not raised. When the circuit is opened from conditions that there are secondary short-circuits or primary voltage abnormally rise, the circuit is automatically returned to the stationary state, and power is supplied to secondary burdens.
