Winding Resistance

Transformers are subject to vibration. A poor design/assembly, overloading or poor maintenance can result in problems and faults. Measuring the resistance of the winding assures the integrity of the connections. The resistance measurements the presence or absence of severe mismatches or opens. Transformers equipped with a tap-changer device involve mechanical movement from one position to another. Resistance testing is the ideal way to prevent failure in such system.

ndb Technologies designs and manufactures high quality Winding Resistance Testers for field or manufacturing applications.
