Winding Resistance Meter |
|
Model : TWRM-40AuP |
|
 |
|
Introduction Winding Resistance Meter is designed to
measure the winding resistance of transformers, Inductors, generators and motor
windings, Tap Changers Etc. It is specially designed for
Highly Inductive objects like 400KV/220KV. This is only indigenous TWRM which
gives very fast readings 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,
Instrument has built in 40A regulated and highly stable current source with
current selection of 40Amp & 10Amp. Instrument uses
ratio-metric circuit where the resistance of specimen is compared with known
internal standard and 4 ½ digit LED/LCD display is provided for resistance
measurement in milliohms and in micro ohms. |
