Abstract :
Effects of humidity, corona, and mechanical stress on the electrical characteristics of porcelain and glass suspension-insulator units are shown in this paper. Moisture, alone and combined with corona, is found to produce surface deposits which cause hysteresis effects in the power, power factor, and capacitive characteristics, and mechanical stress is found to reduce the power, power factor, and capacitance. The effect of stress is reduced where soft metal is used in place of cement in assembling the unit.
