Abstract :
The paper discusses the material properties and designs of stress coatings for cable terminations that can help to reduce the negative effects of the stepped voltages preset in voltage source converters. Simulations using a finite element method in the time domain, as well as experimental measurements of stress grading materials are presented in this study. The use of two layers is suggested as an alternative design to reduce the hot spot temperature in conductive stress grading coatings.
