Abstract :
The effect of fluid impregnation in polyethylene is studied by electroluminescence using a semi-conducting polymer needle molded into a plaque sample. The threshold voltage for electroluminescence is measured for two impregnating fluids which do not impair semiconductor conductivity and is correlated with the soaking time. The mechanism of the dielectric improvement by liquid impregnation is discussed.
