Product Description
1. Product introduction
LHJF1000 GISThe partial discharge on-line monitoring and fault location system consists of the local discharge monitoring IED host, UHF local discharge sensor and expert analysis software. When online monitoring IED is used for networking, a set of monitoring server cabinet will be configured, and high-performance industrial control computer, display, keyboard, mouse, UPS power supply, switch and expert analysis software will be installed inside. The GIL/GIS partial discharge signal is monitored on-line in real time, and the measured data is analyzed, processed and comprehensively judged, the insulation state evaluation report of the equipment is given in real time, and the maintenance plan is arranged according to the monitoring results, so as to avoid major power grid accidents caused by equipment failure and ensure the normal operation of the system with the lowest maintenance cost. ZKA series partial discharge UHF sensor is divided into built-in and external two kinds.
