Abstract

Abstract

The paper introduces a method of monitoring in real time for DC system insulation using asymmetrical bridge in normal mode, and founds a mathematical model for detecting insulation resistance. Integrated Device of DC Insulation Monitoring and Earth Point Locating Based on Microcomputer has been developed. The practical apply proved that the device provides with advantages such as working reliable and running accurate.
