Handheld Ultrasonic PD Detector Partial Discharge Tester for Switchgear Transformer Power Cable
Product Description
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.
Application
1. Power generation and power distribution enterprises.
2. Railway system.
3. Power supply system for petrochemical industry.
4. Aerospace testing.
5. Automatic detection
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.
