The WRM-10P S2 is Vanguard's second generation lightweight winding resistance meter 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, and four-wire (Kelvin) connections provide high accuracy and require no lead compensation. The WRM-10P S2 provides stable resistance readings of very large transformers by utilizing a 36Vdc power supply capable of outputting up to 10 Amperes. 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 S2 comes with a built-in 2.5" wide thermal printer used for printing test reports.

• Auto discharge circuit for operator safety

• Digital resistance reading from 1 micro-ohm to 2,000 ohms
• Stores 100 records (up to 64 readings each)
• Built in 2.5" wide thermal printer
• Weighs less than 28 lbs.
