Transformer Testers effectively measure the turns ratio, winding resistance, tap changers, excitation, and polarity of power instrument and distribution transformers. Transformer Turns Ratio Test Set (TTR) is available in single and three phase configurations. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core. Transformer Ohmmeters are specifically designed to measure the DC resistance of magnetic windings. Other popular kinds of Transformer Test Set include complete transformer test systems, current transformer testing systems, transformer insulation testing, and more. Transformers are faced with large amounts of power coursing through them, and even the smallest issue, if not kept in check, can lead to potentially dangerous consequences. It is crucial not only to check transformers regularly, but to ensure the transformer testing equipment that you use is properly calibrated for accurate results. At TRS-RenTelco we ensure that all our equipment meet calibration standard. We also offer customer support 24/7.
