Product Description 30A Transformer Winding Resistance Ohmmeter Introduction It is used for testing, installing and exchanging the semi-finished or finished transformer. It's also a necessity for power department to do preventive trials. It can effectively help you to find disfigurements in the manufacturing of transformer such as the winding choosing, welding, loose joints, missing shares and hidden danger in the running. In order to meet the need of fast measurement of DC resistance, our company makes use of our technological advantage to develop the Micro Ohmmeter; Features It's suitable for large-scale transformer above240MVA in temperature rising tests.840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate. Dual-channel shows the measurement data at the same time. Each interval of 60 seconds automatically print data. Equipped with temperature conversion software, curve waveforms.Specifications ItemGDZC-2GDZC-10GDZC-20GDZC-40GDZC-100GDZC-20STest current2A10A20A40A25A,50A, 100ASingle phase:1A,5A,10A,20A, 40AThree phase: 1A, 5A, 10A, 20AMeasuring range1μΩ~4.5kohm1μΩ~20kohm1μΩ~10kohm1μΩ~10kohm50μΩ-200mΩ(100A)100μΩ-400 mΩ(50A)200μΩ-800 mΩ(25A)Single phase:10mΩ~20Ω(1A)1 mΩ~4Ω(5A)1 mΩ~2Ω(10A)1 mΩ~1Ω(20A)1 mΩ~0.5Ω(40A)Three-phase:10 mΩ~6Ω (1A,each phase)1 mΩ~1Ω (5A,each phase )1 mΩ~0.6Ω (10A,each phase )1 mΩ~0.3Ω (20A,each phase )Resolution1μΩ Max.
