Description
This instrument is a multi-function measuring instrument, which is equivalent to the usual two kinds of test instruments: the active transformer capacity tester and the transformer characteristic parameter tester. In the characteristic test, it can be tested by the traditional two-meter method or the standard three-wire four-wire tester. The phase system test can not only compare the parameters with the traditional test method, but also accurately measure the parameters. It can accurately measure a series of power frequency parameters such as capacity, type, no-load current, no-load loss, load loss, impedance voltage, etc. of various transformers. The accuracy of capacity and characteristic test results is 100%. The capacity measurement range: 10kVA~100000kVA.
