Product Description

JF-2004 Portable Switchgear and Transformer Partial Discharge Detector

Product Description

JF-2004 Portable Switchgear and Transformer Partial Discharge Detector is used for the detection and evaluation of the insulation status of high-voltage switchgear, ring network cabinets, transformers, GIS, overhead lines, cable terminals, cable branch boxes and other equipment.

 Partial discharge intensity detection: By measuring the discharge signal within a power frequency period, the intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.

Partial discharge frequency detection: The device measures the discharge signal within a power frequency period, extracts discharge pulses and characterizes the frequency of partial discharges according to the number of discharge pulses.

Features

1. Configure different sensors to realize partial discharge detection of almost all electrical equipment;
   
   Humanized man-machine interface facilitates data management of different devices, including traceback of historical data change trends, horizontal and vertical data analysis, and realizes 360 ° comprehensive diagnosis of the device under test;
   
   Built-in ultrasonic sensors and transient ground voltage (hereinafter referred to as TEV) sensors, which can be connected with special sensors such as transformers, GIS, overhead lines and cables;
   
   Adopt non-intrusive detection method, no power failure during the test, maybe no high voltage source is applied, which is more convenient to use than traditional pulsed partial discharge detector;
   
   The test bandwidth range is 30kHz ~ 2.0GHz, suitable for the detection principle of various frequency bands;
