Description
Overview
GAOTek circuit breaker line tester is one online pd tester, it supports four means of partial discharge (PD) detection acoustic emission (AE) pd detection, ultra-high frequency (UHF) pd detection, high frequency (HF) pd detection and transient earth voltage (TEV) pd detection. any combination of the four methods can be configured on one detector. the system adopts Windows ce6.0 operating platform and provides various means of display, such as line, ellipse, sine, flight, 2 d, 3 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. most of the control parameters are set digitally. the system is of small size and lightweight, has strong anti-interference ability, is convenient to use, and has stable performance and good measurement accuracy. it is widely used in online surveying and localization of PD in transformers 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 online surveying of power installations.
