Abstract
The effect of droplets on the surface of the overhead insulators (porcelain and silicone rubber) and their contributions to electric field distribution and hence possibility of failure is investigated. Initially the variation of electric field distribution around a typical water droplet in the sheath and shed regions as a function of contact angle is investigated. The effect on field distribution in presence of multiple droplets is explored by varying the number, the relative positioning and contact angle.
