Transformer Short-circuit Impedance Tester
Features#65306;
The instrument comes with an adjustable power output. Regardless of single-phase or three-phase transformers, only one connection is required, and the instrument can complete the measurement of all winding pairs. The test and connection are simple.
In addition to supporting internal power supply test, it also supports external voltage regulator power supply test.
Meet the test and algorithm specified in "DL/T1093-2008 Guide for Detection and Judgment of Power Transformer Winding Deformation by Reactance Method"
Phase-locked loop technology is used inside the instrument to sample AC signals synchronously, and the measurement data is accurate. |
