Abstract:
A system and method for monitoring a dielectric state of high voltage equipment. A leakage current is measured and compared to a programmed limit value. An alarm is activated if the leakage exceeds the limit value to indicate that insulation has seriously deteriorated. The leakage current measurement is verified using a comparison of individual leakage currents with a change in a vector sum of leakage currents.
Abstract(Chinese):

一种用于监测高压设备的介电状态的系统和方法。 测量泄漏电流并将其与编程的极限值进行比较。 如果泄漏超过极限值，则报警被激活，表示绝缘严重恶化。 使用各个泄漏电流与漏电流的矢量和的变化进行比较来验证漏电流测量。
