Development of Contact Resistance Measurement Device for GIS Main Circuit Contacts
摘要
The contact resistance of GIS contacts is related to the stable operation of the power system. In this paper, a GIS contact resistance measurement device based on the pulse current method is developed on the FPGA platform, which accurately measures the time-domain curve of contact resistance by compensating for the influence of inductance, which is of positive significance for further evaluating the contact contact state.
