A New Leakage Flux-Based Technique for Turn-to-Turn Fault Protection and Faulty Region Identification in Transformers

What is it about?

This technique uses a new and simple sensor in transformer to measure the leakage flux in various cases specially turn to turn fault (TTF), over fluxing, energisation and so on. This effective sensor a printed circuit board (PCB) which can detect the TTF in the transformers.

Why is it important?

TTF in transformer can cause the catastrophic event in the power system. So, TTF detection is really important for each system. This method not only can detect the TTF, but also can localize the faulty region.
