Abstract
This paper attempts to establish a correlation of the visual images of corona obtained
from a camera with discharge magnitude measured with conventional partial discharge equipment. A linear ·'refationship is shown between the transformed image parameters and the discharge magnitude, thereby providing a means for
quantifying corona observations made during routine maintenance inspections of
insulators from ground. Different insulator desigps using silicone rubber (SIR) and
ethylene propylene diamene monomer (EPDM) housings were examined. The effect
of fog has been examined by performing experiments inside a fog chamber. it is
shown that this information can be used along with the c"rona degradation characteristics
of housing materials to identify discharge patt~rus tliat can pose problems
to the integrity of the insulator.
