| Abstract: | Medium voltage cable terminations are widely used for flexible AC transmission(FACTS) and for connecting terminations for electric motors driven by inverters.These cable terminations are possibly subjected to high electrical stress because of high frequency voltage components.In this paper,an experimental setup was designed to test cable terminations insulation under high frequency sinusoidal voltage.A signal generator and a power amplifier were used to generate high frequency voltage and larger output powe... |
