Description
The Vanguard WRM-10P winding resistance meter is designed to accurately measure the winding resistance of highly inductive power transformers. The unit’s dual resistance-reading input channels can measure two winding resistances simultaneously. Four-wire (Kelvin) connections provide high accuracy voltage reading and require no lead compensation. The WRM-10P provides stable resistance readings of very large transformers by utilizing a 36 VDC power supply capable of outputting up to 10A. The resistance reading of a 100MVA transformer can be achieved in 5 minutes or less. The unit’s power supply is cooled by heavy-duty fans designed for continuous operation. For greater flexibility in the field, the WRM-10P comes with a built-in 2.5 inch wide thermal printer used for printing test reports.
