An investigation into the partial discharge (PD) due to electrical treeing degradation in low density polyethylene, ethylene-vinyl acetate copolymer and ethylene-acrylic acid copolymer. Experimental results revealed that the PD magnitude was strongly affected by the instantaneous applied voltage and...
