Measurement of zero-sequence impedance by Balazs Sztari

The zero-sequence impedance on three-phase transformers is important for calculation of asymmetrical fault cases, therefore it is measured during factory acceptance tests. In the 15th lesson of the Transformer testing course, authored and hosted by Balazs Sztari, you will learn how to perform this test and how to understand the results. The hosts will discuss this important parameter for three-phase electrical network design and fault calculations. Join us for free in the live lesson and learn how to measure properly.
