Product Description

Anti-interference Detector of Grounding Resistance for Earthing
Grid

It applies the controlling, sampling, data processing of
microcomputer and displays by the large screen of liquid crystal. Testing the
large erathing grid of power plant and substation by the abnormal frequency
keeps high accuracy and stabilized performance; and efficiently resolves the
industrial frequency current-interference. With only 1～3A testing current and
4kg weight, it greatly eases the labour intensity during the test.

Output current: AC3A or 5A (it can be used with computer
on-line operation, our recommended product with high cost performance)
Output
voltage: AC0～120V
Measuring range: 0～100Ω～500Ω
Measurement error:
＜1%
Connection: trilinear, four-line

In addition, it provides DER2571A/B（ZC-8）type terrameter and multifunctional
grounding terranmeter with double jaw, which is suitable for any grounding
occasions and conditions, and proceeds the online measuring of soil resistivity
and circuit connecting resistance.
