EPBTC Transformer Load / No-load Tester is a high-precision instrument used for measuring characteristic parameters such as transformer capacity, no-load, load, and energy efficiency level. EPBTC is a multifunctional measuring instrument, equivalent to the usual two testing instruments: transformer capacity tester and transformer characteristic parameter tester. It can accurately measure a series of power frequency parameters such as capacity, energy efficiency level, type, no-load current, no-load loss, short-circuit (load) loss, impedance voltage, etc. of various transformers. (Also called Transformer Power Analyzer)
Also called: Transformer Iron & Copper Loss Tester, Transformer load/no-load Tester, Transformer Capacitance and Load No Load Tester
