The present study shows the effects of roomtemperature vulcanizing (RTV) silicone rubber high voltage insulator coatingson the discharge characteristics of a cap-and-pin type suspension glassinsulator. The study covers both laboratory investigations and 3D electricfield analysis, considering the coated and uncoated glass insulators. An ultravioletcorona camera is used to detect the location of the discharges, and a partialdischarge test system is used to obtain the discharge patterns and pulsemagnitudes. The experimental work is only conducted for 50 Hz power frequencyvoltage. In addition to the laboratory investigations, 3D electrostatic fieldanalysis is performed to determine how the RTV coatings on the glass insulatorsaffect the field distributions.
