Coreless transformers (CTs) in solid state isolators (SSIs) rely on inductive coupling to transfer information and power across an isolation barrier. CTs employ near-field magnetic induction coupling, ...

In this paper, we present an update to the models used to calculate the remaining life of transformer paper insulation. A drawback to the current IEEE method is that it does not take into account the ...

Frequency response analysis (FRA) is an effective diagnostic tool for detecting transformer winding movements. Various FRA traces can be measured from a set of transformer winding terminals each of ...
