China Earth Resistance Tester Grounding Resistance Tester Ground Resistance Tester

Product overview
Currently in the power system, it is mainly used frequency large current three-pole measurements to test the ground network earth resistance. In order to prevent frequency interference generated by the power grid operation, to improve the accuracy of the measurement results, insulation preventive test code states: the test current of frequency large current method shall not be less than 30A. Thus, the test equipment is too heavy; the test process is compleEtching Machine x; large work strength, long test time and many other issues.
Ground Network Earth Resistance Tester adopts the new variable frequency AC power, and take advantage of computer processing control and signal processing, to solve the interference problem of testing process, simplifying the test operation process, improve the precision and accuracy of test results, greatly reduce the labor intensity and testing costs.Products features
1. Good frequency equivalence. The measured current waveform is sine wave, the difference between frequency and power frequency is 5Hz, use 45Hz and 55Hz two frequency to test.
2. Strong anti-jamming ability, use different frequency method , assorted with modern hardware and software filtering techniques, Crushing & Culling Machine make the device with strong anti-jamming ability, test results stable and reliable.
3. High precision, intrinsic error 0.005Ω, can test the ground network of small impedance.
4. Powerful: can test current pile, voltage pile, ground resistance, pace voltage, contact voltage.
5. Easy to operate, menu operated, directly display the test results.
6. Do not need high current wire.Technique parametersImpedance measurement range0~200ΩResolution0.001ΩMeasurement error±(readingx2%+0.005Ω)Maximum output voltageAC 400V (45Hz,55Hz, double frequency, sine wave)Maximum output currentAC 3A (45Hz,55Hz, double frequency, sine wave)Current output gear3/2.5/2/1.5/1AAnti-jamming capabilityAnti- frequency 50Hz voltage 10VMeasured wire required valueSection surface of current wire copper core≥1.5 mm2Section surface of voltage wire copper core≥1.0 mm2Power supplyAC 220V±10%,50HzDimension295x340x310mm3Weight28kg
