Online monitoring system for switchgear partial discharge

Product Introduction

Online monitoring system for switchgear partial dischargeUsed for detecting, analyzing, and continuously monitoring partial discharge signals in high-voltage switchgear. The monitoring data is uploaded in real-time to a remote backend to achieve online diagnosis and warning of switchgear insulation status.

Mainly used in high-voltage switchgear scenarios.

Online monitoring system for switchgear partial dischargeKey Features:

Using high-frequency signal detection and analysis technology, real-time online monitoring and analysis of partial discharge inside high-voltage switchgear are carried out to achieve online diagnosis and warning.

Analyze and judge parameters such as partial discharge signal strength, pulse frequency, and discharge frequency, identify partial discharge signals, and remove external noise signal interference.

Equipped with a rich database of partial discharge signals and electromagnetic noise, it automatically analyzes, judges, and identifies detected partial discharge signals.

The sampling and analysis frequency band of partial discharge signals is in the high-frequency band, with strong on-site anti-interference ability and high system judgment accuracy without false alarms.

It has intelligent analysis, positioning, warning and alarm functions, as well as telemetry and remote signal output functions.
