Transformer Winding Resistance Meter is designed to measure the winding resistance of transformers, Inductors, generators and motor windings, Tap Changers, Bus Bar contacts,Power Cables Etc.
It is specially designed for Highly Inductive objects. This is only indigenous microhm meter which gives very fast readings for 3Phase Star-Delta any combination The built in open circuit Voltage of DC Supply ensures that core of the transformer is saturated for fast measurements to be taken.
Care is taken to absorb the Back emf of such transformers.For user safety, Indication for discharges is provided on front panel, if the current through winding under measurement is disturbed/discontinued.
Instrument has built in 1A regulated and highly stable current source with current selection of 1Amp, 100mA, 10mA and 1mA.Instrument uses ratio-metric circuit where the resistance of specimen is compared with known internal standard and 3½ digit LCD display is provided for resistance measurement in micro-ohm, milliohms and in ohms.
