Electrical test of transformers

Periodic electrical tests have been proven to be an effective way of thoroughly understanding the operating state of the transformer and extending its life. Mechanical changes in windings, contact problems at the tap-changer or other connection points, short-circuits in windings or breaks or short-circuits on parallel lines are factors that can be diagnosed quickly. However, these traditional test methods rely on the measurement of many parameters such as short-circuit resistance, transformation rate, magnetizing current, voltage winding resistance and dynamic winding resistance. Turning. In our test system, all these parameters can be easily determined using a single device. Once the test is finished.
Here is an article of our transformer tests with professional equipment:
