Industrial Electrical Testing: Winding Resistance Meters

Winding resistance is defined as the resistance of a length of copper wires from one end to the other. It is a measurement of DC voltage and current in regard to Ohm’s law, where R (resistance) is equal to V (voltage) divided by I (amps). Measuring winding resistance is important, because it can identify problems not easily found through other testing processes. Winding Resistance Meters can identify and diagnose Resistive connections (both internally and externally), partial blowout, shorting in the windings, improper coil or group connections, and more. Winding Resistance Meters are generally used to measure the winding resistance of transformers, chokes, induction coils, heater coils, generators, and an assortment of other motors where no brushes reside in series with the circuit. Advanced Test Equipment Rentals carries Winding Resistance Meters by top manufacturers like Biddle, Electrom Instruments, DV Power, and more. Test with Winding Resistance Meters from ATEC for long or short-term rent.
