The present study shows the effects of room
temperature vulcanizing (RTV) silicone rubber high voltage insulator coatings
on the discharge characteristics of a cap-and-pin type suspension glass
insulator. The study covers both laboratory investigations and 3D electric
field analysis, considering the coated and uncoated glass insulators. An ultraviolet
corona camera is used to detect the location of the discharges, and a partial
discharge test system is used to obtain the discharge patterns and pulse
magnitudes. The experimental work is only conducted for 50 Hz power frequency
voltage. In addition to the laboratory investigations, 3D electrostatic field
analysis is performed to determine how the RTV coatings on the glass insulators
affect the field distributions.
