Overview Current transformer volt-ampere characteristic tester Only need to set the test voltage, current and step, the device will boost and trace voltage current characteristic test curve automatically, save the cumbersome labor of manual pressure regulation, artificial record, tracing curves, and so. Quick, simple and convenient. I can not only test CT/PT DC resistance, volt-ampere characteristics, ratio and polarity, 10% error curve, angle difference and ratio difference, but also test secondary load of transformer, CT current test and PT AC withstand voltage test. CT ratio not only supports traditional current method but also voltage method, so it can meet the test of CT in casing CT and GIS. Volt-ampere characteristic test single machine output voltage 0-2500V, current 0-20A, can meet most of the transformer volt-ampere characteristic test. 220V single power input and avoids the risk of using 380V.
