Hipot GDF-3000A DC Ground Fault Locator

DC system insulation faults, DC mutual faults and AC power failures are faults that are prone to occur and are harmful to the power system, and endanger the normal operation of the power system.Product Features:-● High reliability designThe device adopts imported 32-bit microcontroller as the main system, and the hardware design strictly follows the power and electromagnetic compatibility related standards. The internal redundancy mode is adopted to ensure the reliability of the device and the device under test.● Precision material selectionThe device adopts high-precision collector as the signal acquisition unit, and the voltage sampling adopts high-precision imported analog-digital conversion chip, voltage and impedance are measured accurately;● Humanized human-computer interaction interfaceBoth the analyzer and the detector use a TFT liquid crystal display for users to view information;The operation is simple and fast, and when the detection of different branches is realized, only one start button can be completed;The test results are straightforward and the test results can be presented to the user in a variety of display formats, including grounding or not waveform, insulation levels, insulation resistance, leakage current, and direction information.● Intelligent detection and recognition systemThe analyzer automatically recognizes the system voltage level;The analyzer can determine the ring fault category;After the detector and analyzer information are synchronized once, it will not affected by the detection distance;When the detector is inspecting, the collector 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 a ring network or insulation fault, the direction information of the fault point relative to the test point is determined.● Complete testing function and ability to handle faultsThe wireless data transmission module is built in between the analyzer and the detector for communication. The test function and display information are complete, and can deal with various ring networks and insulation faults in the DC system.The analyzer has a variety of combined working mode by selecting functions of “Amplitude Modulation”, “Waveform” and “Mode”, which can adapt to various complex application environments.● High securityThe device adopts the micro-amplitude detection signal and the high-resolution DC detection collector to realize fault detection and positioning, and has no influence on the DC system.Specification:-Specifications of AnalyzerWorking VoltageDC 22-300V.Environment temperature-20℃—55℃Relativity humidity0—90� voltage measurementDC voltage measurement range22-300VDC voltage measurement resolution0.1VDC voltage measurement accuracy±0.5% @ 220V DC power supply(180V-286V)@110V DC power supply(90V-143V)AC voltage measurement Measurement AC and DC string voltage10-280vAC voltage measurement resolution0.1VAC voltage measurement accuracy0.5%Insulation resistance measurementInsulation resistance measurement range0-999.9KΩInsulation resistance measurement resolution0.1KΩ Insulation resistance measurement accuracy≤±5% Ri <10KΩ display specific value10KΩ≤Ri≤500KΩ ±5�tect bridge amplitude adjustment range 0mA, 0.25mA, 0.5mA , 1mA, 2mADetect ring network resistance rangeless than 50KΩSystem distributed capacitance measurementSystem distributed capacitance measurement range0-999.9uF  accuracy C <10uF or C>200uF: display specific value; 10uF≤C≤200uF: ±10% or ±3uF;Detection waveform type selection: sine wave, square wave;System ground resistance measurement0-1000kΩDetection waveform type selectionsine wave, square waveWorking modeforced signal start, automatic signal startDisplay media and resolutionTFT, 320x240Specifications of DetectorInsulation resistance measurementInsulation resistance measurement range0-500KΩInsulation resistance measurement resolution0.1KΩInsulation resistance measurement accuracyRi <10KΩ display specific value10KΩ≤Ri≤500KΩ ±10%Spectrum analysis rangeNumber of spectrum analysis channels1Spectrum analysis frequency range0.125-12.5HzFrequency resolution0.125HzCurrent waveform display period8s;Detectable feeder current range0-2A;Current measurement range-100- 100mA;Current measurement resolution0.01 mADisplay media and resolutionTFT, 320x240Wireless communication technical indicatorsRate2Mbps, because the air transmission time is very short, the collision phenomenon in wireless transmission is greatly reduced.Multi-frequency point 125 frequency points, meeting the needs of multi-point communication and frequency hopping communicationUltra-smallbuilt-in 2.4GHz antenna, small size, 15x29mmLow power consumptionWhen operating in the answer mode , fast air transmission and start up time greatly reduce current consumptionBuy DC Ground Fault Locator online in India at wholesale rates.
