Transformer Winding Resistance Ohmmeter
Product Code : 17
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!
