GIS partial discharge online monitoring system

This system can be used for real-time monitoring of the partial discharge status of GIS of 126kV and above. It can automatically convert partial discharge activity data into graphics and management report formats and upload them to the server, automatically send out alarms for the degree of danger of partial discharge activities, notify users by email or SMS, and provide auxiliary analysis and maintenance of GIS status Basis for decision-making.

Product description

Parameters

1) Minimum measurement accuracy: -75dBm or (2 meters from the discharge source) Maximum pulse resolution: 10us

2) Ultra-high frequency (UHF) range: 300MHz-1500MHz standing wave ratio Z< 2

3) Measuring period: 2 seconds (adjustable)

4) Display mode: discharge amplitude Q, discharge phase φ, discharge times N, three-dimensional spectrum N-q-φ, amplitude-time relationship, amplitude-phase relationship, discharge times-phase relationship

5) Using SART neural network algorithm, it can identify 4 basic typical discharge types: suspended conductive particle discharge, tip burr discharge, insulator contaminated surface discharge, internal air gap discharge.

6) IED interface and communication protocol: RJ45 network port, IEC61850 communication protocol
