Abstract :
Recently, various kinds of extreme exciting conditions, such as the ac-dc hybrid excitation, are applied to transformers, reactors etc. with the development of the HVDC system. The modeling and estimation of stray-field losses are of increasingly importance in the electromagnetic design of such devices, and it is challenging to measurement and numerical analysis.
