Winding Resistance Meter
Elmon’s SG Series are high current microprocessor based Automatic Transformer Winding Resistance Meter to measure the D.C. resistance of power transformers and other high inductive electrical devices. With fast initial settling time this ohmmeter provides the best overall solution to DC resistance testing of transformers. Single or dual channel measurement of primary or primary and secondary transformer winding resistance is displayed on a large Graphic LCD screen. The measurement is based on four wire ratio method which eliminates the requirement of lead compensation. The meter is equipped with correct polarity check and indication of charging and discharging of transformer winding.
