Abstract :
Analysis the Factors of devices tanδ on-line monitoring, in the paper, by using shield method and the coefficient correction method eliminates the impact of external effectively , And by changing sampling method of voltage signal to resolve the phase angle error of voltage transformer effect; By using a triangular window FFT method to solve the traditional algorithm the problem ; Thus, to meet tanδ on-line monitoring of variety voltage devices requirements, provide the conditions for state maintenance of devices.
