5A /10A / 20A / 50A Portable  Transformer Winding Direct Current DC Resistance Tester Winding Resistance Meter

  • Introduction:
  1. It is used for testing, installing and exchanging the semi-finished or finished transformer.
  2. It is also a necessity for power department to do preventive trials.
  3. 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.
  4. 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:
  1. It is suitable for large-scale transformer above 240MVA in temperature rising tests.
  2. 840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
  3. Dual-channel shows the measurement data at the same time.
  4. Each interval of 60 seconds automatically print data.
  5. Equipped with temperature conversion software, curve waveforms.
