Product Description

 

Products Introduce

 

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 lines, cables and other equipment. The discharge degree of electrical and gas equipment is measured by the following indicators:

 
Partial discharge intensity detection: measure the discharge signal within one power frequency cycle, and characterize the partial discharge intensity according to the maximum value (dB) in the discharge pulse sequence.

Partial discharge frequency detection: measure the discharge signal within one power frequency cycle, extract the discharge pulse and characterize the frequency of partial discharge according to the number of discharge pulses.

Product characteristics

Configure different sensors to realize partial discharge detection of almost all electrical equipment; The
humanized man-machine interface facilitates the data management of different equipment;
Built in ultrasonic sensor and transient earth voltage (hereinafter referred to as TEV) sensor, which can be externally connected to transformers, GIS, overhead lines, cables and other special sensors;
Non intrusive detection mode is adopted, so there is no need to cut off power and configure additional high-voltage source duringthe test, which is more convenient than the traditional pulse type partial discharge detector;
The test bandwidth range is 30kHz~2.0GHz, applicable to the detection principle of various frequency bands;
