GAOTek Dc System Ground Fault Tester

Description

Overview

GAOTek dc system ground fault tester present, the core problem of power system DC power supply grounding fault search is that the field interference is large, in different DC power supply and different working conditions measurement, most of the products will miss detect and misjudge, poor anti-interference. Sinusoidal signal phase processing technology and data transfer algorithm technology are used to develop and produce. This product is between the two types of fixed and mobile, the use method is mobile, the performance is online fixed, to find the DC system grounding fault, do not need to disconnect the power, can achieve ground location. The instrument can not only detect the grounding resistance value of DC system, but also detect the grounding capacitance capacity of DC system, which provides a suitable and reliable high accuracy detection instrument for the search and location of the grounding fault of power DC system.

Features
