Flashover characteristics of a droplet impacting the silicone rubber surface

The surface discharge of silicone rubber (SIR) is one the main reasons to accelerate aging its material in power systems. It known that static water droplets on SIR can make flashover voltage substantially fall, while characteristics impacting are unknown. In this work, dynamic studied. When impact surface, they will stretch first and then shrink. minimum occurs at moment when spreading area droplet reaches maximum, drop nearly 1.8 times droplet. begins shrink, bright arc turns into a filament-like disappears as continues At same time, falls large height, be broken under action electric force, likely further fall.
