Product Description

 Product introduction

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

 

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

 

Partial discharge frequency detection: extract discharge pulses by measuring the discharge signal in one power frequency cycle, and characterize the frequency of partial discharge according to the number of discharge pulses.

 

 Product Features

1.Simultaneous interpreting PD signals of almost all electrical equipment with different sensors.

2. Humanized man-machine interface facilitates data management of different equipment;

3.Built in ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, which can be connected with special sensors such as transformer, GIS, overhead line and cable;

4. The non-invasive detection method is adopted, so there is no need to cut off power and configure additional high-voltage source in the test process, which is more convenient than the traditional pulse partial discharge detector;

5. The test bandwidth range is 30kHz -2.0GHz, which is applicable to the detection principle of various frequency bands;

 

Application

1.Electric Power generation and distribution enterprises

2. railway system

3. Petrochemical Power Supply System

4. Aerospace testing field

5.Automatic detection field
