Watch video · Cleaning high voltage insulators are important to maintain the insulator operating and insulator service time. Photo: Composite Insulator If bushings are not periodically cleaned, a phase to ground fault can occur when corona nears the grounded transformer tank, potentially destroying the bushing and causing an extended outage.

apparent advantage over cap and pin insulators in that metal fittings exist only at the ends of the insulators. Bushings Bushings are used to insulate the conductors of the high voltage ter-minals of a transformer as is shown schematically in figure 5. Traditionally, transformer bushings are manufactured using porcelain.
