GDJF-4
Handheld Ultrasonic PD Detector Partial Discharge Tester for Switchgear Transformer Power Cable
Introduction
Partial discharge (PD) is an important parameter to characterize the insulation performance of high-voltage electrical equipment, and it is also an effective precursor information for insulation failure. Through the detection of partial discharge, especially on-line monitoring, it will create conditions for avoiding accidents and implementing condition-based maintenance.
Our GDJF-4 Handheld Ultrasonic PD Detector is a very convenient device for testing the discharge degree of electrical equipment.
Function
1)Connect with different sensors to achieve partial discharge detection of almost all high-voltage electrical equipment;
2)Provide time domain waveform, PRPD, PRPS and other discharge patterns to realize the analysis of different discharge types.
3)Built-in ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, which can be connected with special sensors such as transformers, GIS, overhead lines, cables, etc.;
4)The test bandwidth range is 30kHz-2.0GHz, which is suitable for detection principles of various frequency bands;
5) Handheld and light weight,only about 0.5KG for host, easy to use in the field.
