Monitoring of winding hot-spot temperature and dissolved gas-in-oil and furan-in-oil provides a major support to the operator when the transformer faces overload conditions. On-line monitoring of ...

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

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 ...
