Large Grounding Grids Network Earth Resistance Tester 3A - 5A For Power System

 

Introduction

This device applies to test power-frequency ground resistance, contact voltage, pace voltage and earth electric resistivity. Can test substation grounding grid (4Ω), fire and water electric power plants, microwave stations (10Ω), lightning rod multi-purpose model (10Ω). It adopts different frequency anti-jamming technique, can get the data under 50Hz in strong interference circumstance. The maximum measured current is 5A, which will not cause the electric potential of the grounding device too high, it with strong anti-interference ability at the mean time, so it does not need power off during the test .

 

Features

1. Good power frequency equivalence for measurement.

The waveform of test current is sine wave and the difference between frequency and power frequency is merely 5Hz. 45Hz and 55Hz frequencies are used for measurement.

2. Strong anti-jamming capability.

This instrument takes pilot frequency method for measurement and matches with the modern software and hardware filter technology so as to achieve high anti-jamming performance and stable and reliable testing data.

3. High precision.

Since the elementary error is only 0.005Ω, it can be used testing the large earthing grid with small grounding impedance.

4. Powerful function. It can measure Pill-I, Pill-U, grounding resistance, Grid grounding resistance, on resistance, soil resistivity .

5. Simple operation.

6. Small wiring labor cost, with no need of large current lines.
