High Class Winding Resistance Tester

With prosperous industry practice, our entity has gained huge appreciation in the market by exporting and manufacturing and supplying of the High Class Winding Resistance Tester in Gurgaon, Haryana, India. Our customer a large range of Winding Resistance Tester that is checked on varied parameters under the supervision of quality controllers to ensure its quality before the final delivery. Power transformers, instrument transformers, voltage regulators, rotating machines are its application areas. The WRT-10 is a high performance winding resistance tester designed for Power Transformer and large motor applications. Winding resistance testing is an important part of a power trans-former maintenance or a manufacturing quality assurance program. Transformers & large motors are subject to vibrations, overloading and environments with large temperature variations. Winding resistance measurements can assure that the connections are made correctly and that no opens or shorts are present.

Its Operation are
The WRT-10 injects a DC current through the windings & measures the voltage drop. The instrument calculates the resistance R= E / I. The challenge in winding resistance measurements is that the voltage across an inductor is defined by V = L (di/dt), where L is the induc-tance of the winding & (di/dt) is rate of change of current. Therefore small changes in the current, as may be caused by ripple or poor regulation, can make it impossible to measure the DC resistance. The highly regulated and filtered current output of the WRT-10 allows for winding resistance measurements on very large power transformers.
