It is specifically designed for the direct resistance measurement of large-scale power transformers. Below is a detailed description of its main features:

Easy-to-Reach Customer Service

All high and low voltage current potential test wires are connected to the transformer at once, without the need to change or adjust the test wires during the testing process.Extreme.Dirt Streamline the testing process, enhancing work efficiency.

Three-phase Test Function

For the star connection winding, the tester can simultaneously conduct three-phase tests.A0、B0、C0The resistance testing, significantly shortened the time required for the test.

During the three-phase test, first test individually.A0Data was collected, followed by simultaneous three-phase testing, which resolved the issue of untestable neutral lead resistance, resulting in test data that is closer to the actual single-phase test values.

Automatic Magnetization Technology:

During low-voltage testing of transformers with three-phase and five-column internal angle connections, the instrument employs an automatic magnetizing method. Compared to traditional high-current testing, this method offers faster testing speeds, enhancing efficiency.
