GDF-3000 DC System Earth Fault Detector

GDF-3000 DC System Earth Fault Detector

In DC system, there are many earth faults including indirect earth fault, non-metal earth fault, loop earth fault, positive and negative earthing fault, positive and negative balance earth fault, multi-point earth fault. GDF-3000 Earth Fault Tester for DC System locates these earth faults and displays the parameters of system voltage, earth voltage, earth resistance and earth impedance of branches accurately.

● System ground voltage measurement function, the instrument can measure the system ground voltage, negative to ground voltage, system voltage, can achieve 0-300V voltage monitoring range.
● System insulation impedance measurement function, the instrument can measure the positive to ground insulation impedance and the negative to ground insulation impedance of the system. It can realize the measurement of 0-999KΩ.
● AC string electrical detection function, the instrument can judge the AC string electrical failure in the DC system, and can measure the AC voltage value that enters in the DC system, the AC voltage measurement range is 0-280V.
● Branch insulation impedance measurement function. The instrument measures the positive and negative ground insulation impedance of each branch.
● Branch grounding fault point positioning function, the instrument can achieve the grounding fault point positioning function of the branch grounding fault.
● Ammeter function, the device can be used as a high-precision ammeter, and the current measurement resolution can reach 0.01mA.
● With a non-signal ground search function, the device can locate the ground fault point without injecting any signal into the system.
● Direction display function, for testing the branch with ground indication, the instrument will have a direction indication arrow to indicate the relative direction between the user's grounding point and the found grounding point, to improve the search efficiency.
● Insulation index analysis function, when using the grounding function detection, after detecting a branch, the detector will display the insulation index of the branch for user reference and analysis.
● The waveform curve display function, when using the detector to detect the insulation condition of the tested branch, the display will display the current change of the measured branch in the form of a waveform curve, which is convenient for the user to quickly and accurately find the fault point.
