一种电容型设备介质损耗角正切的监测方法

摘要

电力系统当中的电力设备按照其绝缘结构分类，电容型设备占有很大一部分。这类设备的特点是高压端对地有较大的等值电容。对于该类设备而言，通过对其介电特性的监测可以发现尚处于早期发展阶段的绝缘缺陷。%According to the insulation structure classification of the power equipment in power system,capacitance type oc-cupies a large part of the equipment.This kind of equipment is characterized by high pressure side to have bigger equivalent ca-pacitance.For this kind of equipment,and it can find insulation defects at the stage of early development by monitoring its dielec-tric properties.
