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.

● The imported 16-bit microcontroller is used as the main system. The hardware design is strictly in accordance with the relevant standards of power and electromagnetic compatibility. Multiple redundancy methods are adopted internally to ensure the reliability of the device and the device under test.
● The high-precision DC clamp meter is used as the signal acquisition unit, and the voltage sampling adopts high-precision analog-to-digital conversion chip, and the voltage and impedance are accurately measured.
● LCD display, with friendly interface, clear and easy operation. Display insulation index vividly and real-time display waveform. It reflects insulation level of every branches and earth fault direction.
● Intelligent detection and recognition system.
● The "analyzer" can automatically identify the voltage level of the system, and display the information of the insulation impedance quickly when the insulation impedance of the system changes.
● After the detector is synchronized with the analyzer information, it is not affected by the detection distance;
● When the "detector" is inspecting, the clamp can clamp a single power cord, or clamp multiple power cords to improve detection efficiency;
● After the "detector" test is completed, if the tested branch has an insulation fault, the direction information of the fault point relative to the test point is determined.
● The wireless data transmission module is built in between the "analyzer" and the "detector" for communication, and the test function and display information are complete, and can deal with various insulation fault conditions in the DC system.
● The device can locate the grounding fault point without injecting signal into the DC system. In the signal mode, the device has a current limiting and voltage limiting module, which has no effect on the DC system.
