Since the WRM-10P S2 can accurately measure resistances ranging from 1 micro-ohm to 2,000 ohms, it can also be used to measure EHV circuit-breaker contact resistance, motor winding resistance, or any low resistance. If the transformer winding temperature is entered, the WRM-10P S2 can calculate the equivalent resistance value of the winding material (aluminum or copper) at any standard reference temperature.
Also, a special test mode can run a test for up to 60 minutes while saving resistance readings at 10, 15, 20, 30, or 60 second intervals. In addition to measuring the resistance value, the WRM-10P S2 also checks the “make-before-break” tap-switching sequences of voltage regulators and load tap changers.
The WRM-10P S2 can store test results in Flash EEPROM. Test results can be printed on the built-in 2K-inch wide thermal printer or can be transferred to a PC via the USB PC or USB Flash drive interfaces.
The WRM-10P S2 is furnished with three 50-foot test cables. Each test cable lead is terminated with a quick-disconnect test clip.
