Abstract

PURPOSE: To facilitate maintenance, by discriminating the short-circuits at the secondary side and the abnormal rise of voltage at the primary side of this transformer for condenser type meters, and by operating a protective device and an alarm device when there are secondary short-circuits and the alarm device when primary voltage abnormally rises.
CONSTITUTION: A main condenser C1, a partial-pressure condenser C2, a leakage transformer T, a relay RY1 for detecting abnormal voltage and a relay RY2 for detecting secondary short-circuits are connected among fixed terminals. When there happen the accidents of short-circuits betwenn secondary terminals, the relay RY1 does not function, and the relay RY2 acts to give alarms. When voltage at the primary side abnormally rises, the relay RY2 does not work, and the relay RY1 operates to raise alarms. When the circuit is opened from conditions that there are secondary short-circuits or primary voltage abnormally rises, the circuit is automatically returned to the stationary state, and power is supplied to secondary burdens.
