Product Introduction

This product can be widely used in partial discharge detection of power system, including high voltage switchgear, ring network cabinet, voltage / current transformer, transformer (including dry type transformer), GIS, overhead line, cable and other equipment insulation state detection, through the following indicators to measure the discharge degree of electrical equipment

Partial discharge intensity detection: by measuring the discharge signal in one power frequency cycle, the partial discharge intensity is characterized according to the maximum value (dB) in the discharge pulse sequence

Partial discharge frequency detection: by measuring the discharge signal in one power frequency cycle, the discharge pulse is extracted and the partial discharge frequency is characterized according to the number of discharge pulses.

Product Names：partial discharge detector、ultrasonic partial discharge detector
