(106 Reviews)

Applications:

A Partial Discharge (PD) Tester, also known as a PD Detector, is a device used to measure and analyze partial discharge activity in electrical insulation systems. Partial discharge is a phenomenon that occurs in insulation materials when there is a breakdown of the dielectric strength, leading to localized electrical discharges. These discharges can degrade the insulation and eventually lead to equipment failure.

Profile:

Partial Discharge Tester PD Detector is widely used in on-line surveying and localization of PD in transformers, GIS, SF6 tank circuit breakers, switchgear cabinets, and cable terminals of various voltage levels. The system can effectively find insulation defects, which makes it an ideal tool for on-line surveying of power installations .it has four functions: AE PD detection, transient ground voltage PD detection, UHF PD detection and high frequency PD detection. Designed with patented AE, TEV, UHF, and HF technologies, The system has friendly user interface and high sampling rate, and provides a variety of waveform recording and analysis means to make it easier for you to judge the nature of the discharge.

Features:

Adopts Windows CE6.0 operating platform, and provides various means of display, such as line, ellipse, sine, flight, 2D, 3D, Φ-P/N, Φ-P-N-D, statistics, trend, discharge analysis, and noise elimination. Static or dynamic measurement, observation and analysis of PD pulses in single or multiple cycles of test voltages can be performed.
Small size and light weight, has strong anti-interference ability.
