Transformer Demagnetizer solves the magnetization problem in a transformer. The transformer magnetic core may become magnetized as a result of DC current testing (such as winding resistance measurement), or when the transformer is taken out of service. In order to avoid problems such as the incorrect operation of protective relays, high inrush currents or erroneous […]

Transformer turns ratio tester from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers. All models, except TRT03 and TRT-H series, […]

Winding resistance meter test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. […]
