Transformer Testers
Swipe Right For Featured Transformer Testers
Transformer Testers are frequently used by plant and factory maintenance workers, field technicians, and electrical contractors to predict deviations in turns ratio readings and indicate problems in one or both windings or the magnetic core of transformers. Transformer Ohmmeters are specifically designed to measure the DC resistance of magnetic windings. Our transformer testers effectively measure the turn’s ratio, winding resistance, tap changers, excitation and polarity of power instrument and distribution transformers. Transformer Turns Ratio Test Set (TTR) are available in single and three phase configurations.
