초록

The conventional method used low pass filter for computing resistive leakage current from total leakage current. Therefore, it takes long time for computation. In this paper, a new algorithm is proposed to reduce the computation time. In the theory, the resistive leakage current is computed exactly from the signals during only a half period of power voltage. The suggested method uses integrator and sample-hold circuit and it is confirmed to be able to measure the resistive leakage current from total leakage current by simulation.
