Abstract

In view of the influence of grounding capacitance to low frequency signal injection method, a new detection technology is proposed based on DC bus to grounding capacitance. This method does not affect the normal operation of DC power system. The insulation monitoring devices for DC power system is designed. A prototype test that it is able to monitor the capacitance value of the DC bus to grounding capacitance in real time, send out the alarm information with the larger grounding capacitance and improve the reliability of the DC system, which has the advantages of simple operation, accurate measurement and good stability.
