Abstract

In order to use polarization and depolarization current to diagnose the insulation statement of power transformer oil-paper composite insulation on site, XY conductivity model is put forward and deduced, and the test value of polarization current and depolarization current is used to verify the effectiveness of time domain XY conductivity model with different geometry in simulating the polarization and depolarization characteristic of oil-paper composite insulation, and to analyze the change rule of polarization and depolarization characteristic of oil-paper composite insulation. The results show that XY conductivity model is effective to simulate polarization and depolarization characteristic of oil-paper composite insulation with different geometry. Change of X has a greater influence on polarization and depolarization characteristic of oil-paper composite insulation than change of Y much more. With increasing of X and Y, variation trend of polarization current of oil-paper composite insulation changes little and amplitude decreases, and initial amplitude and rate of descent of depolarization current decreases and curve flattens out.
