Stress grading materials for cable terminations under fast-rise time pulses

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