Product Description

GDF-3000 Portable DC Ground Fault Finder

 

Product Description

DC system ground Fault of the Power system is an Fault that incident and larger jeopardize for Power system, whether it is positive or negative ground Fault, all of those may cause safeguard maloperation or protection refused action, endanger the normal operation of the power system.
 

Features

DC system ground finder judge the system insulation situation and branch insulation fault point by system voltage to ground and leakage current of the various of the branches.
When test point is above the ground fault point, the finder will given the insulation Fault signal . When the test point is below the ground fault point , the finder will given the insulation normal signal . That can located the ground fault point.
DC ground finder include "DC System Analyzer" and "DC Fault Detector", Put the power line of  "DC System Analyzer" in the positive, negative and ground of DC system by marked. Turn on the DC Analyzer, the Analyzer will analyzed the insulation of DC system, and display the System voltage, Positive voltage to ground or Negative voltage to ground , Ac into DC state or AC voltage, Grounding impedance on the LCD. if it detected the insulation Fault of system, User can use the detector to located the ground point.
The "DC System Analyzer" and the "DC Fault Detector"  are through the wireless module for data communication, The Detector equipped with a high-resolution DC Clamp, realize the detection leakage current size of measured branch, at the same time, the Detector through the wireless module reads the grounding voltage signal from the Analyzer, through this voltage and current to achieve detected the insulation resistance of the measured branch.
