摘要
Abstract
Tests should be carried out for on -line SPDs on DC voltage with 1 mA current output, leakage current and operation characteristics under combined impulse wave to verify whether the SPDs are damaged or aged[1]. A combination wave generator with maximum output of 6kV/3kA was designed based on the circuit calculation and sensitivity study of element parameters on output waveforms from EMTP - ATP simulation. It was found that the front time of output waveform was mainly determined by the inductor while the tail time was mainly up to the main capacitance and the equivalent impedance of the discharge circuit branch. The on - site applications show that the combination wave generator is able to measure the operation characteristics effectively, and predicate whether the on -line SPDs are damaged or aged.关键词
