Inverstigation of DC Leakage-current Waveform of Contaminated Insulators

抄録

Leakage currents on various kinds of porcelain insulators were measured under DC voltage application in artificial contamination tests by using powerful DC power source which practically gives no voltage drop against leakage current during the test. Magnitude, duration and waveform of leakage currents were analyzed in relation to kinds of insulators and test procedures.
