介绍了一种利用绝缘介质极化特性在现场检测油纸绝缘总体状态的新方法。
A new method is introduced in this paper for field detection of the general status of oil paper insulation system by using dielectric polarization spectrum analysis. In order to get the return voltage (RV) of the insulation system, a series of tests of charging and discharging were carried out with different time constants. By analyzing the relationship between the RV and charging time, the general status of oil paper insulating system in power transformer can be assessed.
