Volume Resistivity Characteristies of Transformer Oils due to the Stirring Temperalure of BTA
BTA 교반온도에 따른 변압기유의 체적고유저항 특성
Abstract
In this paper, volume resistivity is studied so that the electrical properties for transformer oil due to the stirring temperature of BTA is investigated. A measurement of volume resistivity using the VMG-1000 highmegohm meter is recorded after 10 minutes when the each voltage, and DC 100[V], 250[V], 500[V] and 1000[V] is applied, according to the step voltage appliaction method. A coaxial cylindrical liquid electrode to measure volume resistivity of specimen is used, and its geometric capacitance is 16[pF].
