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 based on winding discretization with inclusion of loss...

This study presents the impact of wind power plant components modelling on harmonics propagation and harmonic small-signal stability studies. Different types of cable and transformer modelling techniques are taken into consideration, e.g. state-of-the-art standard models and latest academic developm...

Offshore umbilical cables often include both power cables and elements such as metallic tubes and signal cables. It was concluded from a recent failure of stainless tubes that AC corrosion was the failure cause. This paper describes how AC corrosion can lead to tube failure if a puncture exists in t...

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 properly reproduce the transformer's input impedance cha...

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-based voltage transfer function model which permits ...
