Product Name: HC8021GIS Partial Discharge Online Monitoring System
Category: Intelligent Online Monitoring System for Substations
Detailed Introduction
Product Introduction
HC8021GIS Partial Discharge Online Monitoring System is a new generation of high-performance digital partial discharge online monitoring device that uses sensor technology, signal processors, computers and other technical means and algorithms. It can operate for a long time and monitor the partial discharge of GIS in real time during operation. It can timely warn of abnormal insulation status and discharge faults of GIS, provide necessary guidance data for the normal operation of GIS, and improve the reliability, safety and effectiveness of GIS operation.
Functional Features
※ Strong anti-interference ability and accurate monitoring data;
※ Several monitoring devices in the station can operate independently, and the data are recorded separately;
※ Provide multiple alarm methods: mobile phone SMS alarm, sound and light alarm, etc.;
※ Realize remote data transmission through fieldbus, telephone network or Internet network, and conduct high voltage
※ Remote online monitoring and operation analysis of electrical equipment;
※ The background management software has powerful partial discharge trend analysis function.
