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.Product Features:-● 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.Specifications:-Use EnvironmentAmbient temperature-30 ° C ~ 50 ° C;Relative humidity≤95%;Wireless communication technical indicatorsSignal power≤ 10dbm;Signal band433Mhz;Sensitivity-106dBm;Transmission distancein the case of line-of-sight, reliable transmission distance of 250 meters from the ground 2 metersAnalyzer technical indicatorsApplicable DC system voltage level24V (customized), 48V, 110V, 220V or user-specified voltage levelSystem positive and negative voltage measurement range0-300VDC voltage measurement range to ground0-300VAC series power failure alarm threshold5VVoltage measurement resolution0.1VSystem ground resistance measurement range0—999.9KΩGrounding resistance measurement resolution0.1KΩDisplay modeLCDDetection signal current size0-2mA adjustableDetection signal voltage amplitude0-50V adjustableSignal frequencyno signal mode and 0.16Hz optionalDC-resistant system distributed capacitance interference1000uFDetector technical indicatorsInsulation resistance detection range of branch circuit in signal modeSystem voltage rating is 220V0 -600KΩSystem voltage rating is 110V0 -300KΩSystem voltage rating is 48V0 -60KΩSystem voltage rating is 24V0 -20KΩInsulation resistance measurement resolution0.1KΩInsulation resistance detection range of branch circuit in no signal modeSystem voltage rating is 220V0 -50KΩSystem voltage rating is 110V0 -25KΩSystem voltage rating is 48V0 -10KΩSystem voltage rating is 24V0 -5KΩInsulation resistance measurement resolution0.1KΩWaveform display time12 secondsCurrent measurement range±100mACurrent measurement resolution0.01mADisplay modeLCDDirection display modesame or opposite directionAnti-DC system branch distribution capacitance interference100uFDistance to use with the analyzerno distance limitJaw sizeDiameter 30mmBuy DC System Earth Fault Detector online in India at wholesale rates.
