Research on a Mixed Method of the On-Line Monitoring of High Voltage Power Cable with XLPE Insulation

摘要

On the base of analyzing the feasible methods to on-line monitoring of XLPE high voltage power cable insulation and simulating the difference frequency method, a mixed on-line monitoring method of low frequency response signal and DC component is presented in this paper. Considering the factors of equipment protection and exclusion of disturbance, computer simulation of monitoring method is processed and every details of realization of control strategy are pointed out.
