Figure 9 - Winding Hot-Spot Temperature Model on a 107-MVA Converter-Transformer For this winding, the rated hot-spot rise above top-oil was estimated by the manufacturer to be 25 °C. For the winding ...

This paper presents analytical expressions for calculating leakage inductance, self-capacitance, and ac resistance in transformer winding architectures (TWAs), ranging from the common noninterleaved ...

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the ...

This paper presents a new concept of air-core transformers, which uses a resonant tertiary winding to create a strong coupling between the primary and secondary transformer windings. A large ...
