Overview

GAOTek earth network grounding resistance tester electric network analyzers for measuring earth resistance 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. This product applies to test frequency ground resistance, contact voltage, pace voltage and earth electric resistivity. Can test substation grounding grid (4 Ω), fire and water electric power plants, microwave stations (10 Ω), lightning rod multi-purpose model (10 Ω).

 

Features

  • Good frequency equivalence. The measured current waveform is sine wave, the difference between frequency and power frequency is 5 Hz, use 45 Hz and 55 Hz two frequency to test
  • Strong anti-jamming ability, use different frequency method, assorted with modern hardware and software filtering techniques, make the device with strong anti-jamming ability, test results stable and reliable
  • High precision, intrinsic error 0.005 Ω, can test the ground network of small impedance
  • Powerful, can test current pile, voltage pile, ground resistance, pace voltage, contact voltage
  • Easy to operate, menu operated, directly display the test results
