Anti-interference Detector of Grounding Resistance for Earthing Grid
Profile:Manufacturer - Producer|Ref:PSL123554YH | Country: China | Currency: | Export: No
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.
