Transformer Direct Current Resistance Test

The Transformer Direct Resistance Tester is a new testing device that integrates magnetic aid testing, three-phase testing, and demagnetization functions. It is specifically designed for the direct resistance measurement of large power transformers. Below is a detailed description of its main features:

Convenient Contacting

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

Three-Phase Test Function

For star-wiring configurations, the tester can simultaneously conduct three-phaseA0、B0、C0Our resistance testing has significantly reduced the time required for the tests.

During the three-phase test, conduct individual tests first.A0Data was collected, followed by a three-phase simultaneous test, thereby resolving 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 the low-voltage testing of a transformer with a three-phase five-column internal angle connection, the instrument employs an automatic magnetic assistance method, which, compared to the traditional high-current testing, offers a faster testing speed and improves testing efficiency.
