    Transformer Strange Inrush Current

    Most of what I have been researching has been related to how POW switching, residual flux in the core, and several other parameters affect the inrush current. I never did find any dependence on how long the machine might be isolated for, but due to the "trend" as well as the constant pushing...

    Transformer Strange Inrush Current

    Hello all, I wanted to gather thoughts on a particular trend that has been observed. The trend is as follows: When a transformer is isolated and then energized, the longer the transformer was in isolation for, the higher the inrush current peak magnitude. Effectively, if the transformer was...

    Transformer "Self" Demagnetization

    Hello, I am doing a study on transformer core magnetization and how it plays a role in the transients seen during energization. One of the things that I was tasked with looking into was why some of the transformers that we work with will demagnetize if isolated from the rest of the network (a...
