Winding Resistance Meter By Elmon Systems Pvt. Ltd.

We are engaged in exporting, distributing and supplying excellent quality Winding Resistance Meter to our valuable clients. SG50WRM is a 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.

SG50WRM is suitable for use in the charged switchyard up to 765 kV. In addition the special circuits employed limit the L di/dt effects that can give rise to noise and unstable readings. The built-in data storage, interfacing to PC, thermal printer & discharge circuit features makes it suitable for a wide range of factory, on-site measurement.
