White-box models are detailed models for the investigation of the internal behavior of transformers during dielectric design. A new model of this type with significantly improved characteristics is presented in this paper. The model has been develope

White-box detailed transformer models are used by manufacturers for predicting internal overvoltages in transformer windings during the lightning impulse test. One such model is the d-factor model which is based on a lumped-parameter description base

Transformer manufacturers make routine use of white-box detailed transformer models for ensuring that the transformer will pass the lightning impulse test. For use in general simulation studies, the model should additionally be multi-phase and proper

Transformer terminal equivalents obtained via admittance measurements are suitable for simulating high-frequency transient interaction between the transformer and the network. This paper augments the terminal equivalent approach with a measurement-ba

The transformer manufacturers make use of electromagnetic transient calculations by detailed white-box models to ensure that the transformer will withstand the lightning impulse test during the factory acceptance test. In principle, such models could

The standard lightning impulse voltage wave used in transformer factory testing does not properly cover all the overvoltage stresses that a transformer can experience while in service. To properly asses the internal overvoltages that can occur in pra
