Internal Arc Performance of Instrument Transformers Filled with Different Dielectric Liquids
EnergiesInternal arc testing is still a controversial topic in the instrument transformer world. The main reason for that is the fact that even a fully successful test guarantees only a certain degree of transformer safety. Furthermore, the test does not cover a
