Transformer Winding Resistance Meter
This ZRS series transformer winding resistance meter is the newest instrument for measuring DC resistance of big power transformers windings. It's able to measure three windings simultaneously and it has auto-discharge circuit for operator safety, for OLTC transformer, discharge no needed. Test duration is only one third than conventional single-phase DC meter.
The transformer winding resistance meter adopts large-size LCD displayer and graphical interface displaying. It is equipped with built-in thermal printer with big-capacity storage and is portable, light weight, no more than 13kg.
