GIS Partial Discharge Online Monitoring System

Product Introduction

GIS Partial Discharge Online Monitoring SystemIt can monitor the partial discharge of high-voltage electrical equipment such as GIS in real-time during operation, and provide timely warnings for insulation abnormalities and discharge faults of the equipment, achieving digitalization of substation maintenance.

Mainly used for GIS equipment of various voltage levels.

GIS Partial Discharge Online Monitoring SystemMain functions:

Avoiding the main electromagnetic interference frequency bands in the power grid, it has good resistance to electromagnetic interference and is insensitive to vibration and noise;

It is sensitive to various discharge defects, and even with external sensing detection methods, it can achieve sufficiently high detection sensitivity;

Based on the waveform characteristics of discharge pulses and the spectral characteristics of UHF signals, fault diagnosis and localization can be carried out;

Large effective detection range, few detection points, high detection efficiency, suitable for online monitoring.
