Partial discharge of cable joint on line monitoring system

Introduces a cable partial discharge on-line monitoring system. Analysis the mechanism of cable joint partial discharge, analyze the transmission characteristics of broadband current with current transformer that measures the partial discharge. Mainly introduces the composition and architecture of on-line monitoring system for Cable Partial discharge. The on-line monitoring system is installed in the field, running well. Practice has proved that the on-line monitoring system for partial discharge of cable joints accurately.
