ABSTRACT: Fast Fourier Transform (FFT) algorithm can be used to measure the dielectric loss angle
of high voltage electric equipment, but the measurement accuracy is ease to be influenced by leakage
effect of asynchronous sampling. In this paper, leakage effect of FFT algorithm caused by asynchronous
sampling is ...
