Product Description

Transformer winding resistance ohmmeter

Description of winding resistance ohmmeter

  • This ZRS series transformer winding resistance ohmmeter is the newest instrument for measuring DC resistance of windings of big power transformers. It may measure three windings simultaneously!
  • There is auto-discharge circuit for operator safety.
  • For OLTC transformer, there don’t need discharge. Test duration is only one third of those by conventional single-phase DC meter.
  • It adopts large-size LCD displayer, graphical interface displaying.
  • It is equipped with built-in thermal printer and big-capacity storage.
  • It is portable, light weight, not more than 13kg!
