Flashover:- Flow of leakage current from line conductor to pin to the outer surface of insulator is known as flashover. Puncture:- If leakage current flows from line conductor to pin through body of conductor. This is known as puncture. Creapage Distance:- The shortest distance through which leakage current flow from line conductor to pin is known as Creapage distanc...

The purpose of insulator is that it resist the flow of leakage current.Insulators provide proper insulation between line conductor and tower. Properties of insulator:- A good insulator must have the following properties. 1-High mechanical strength. 2-High electrical resistance. 3-High relative permitivity. 4-High dielectric strength. 5-To bear maximum wind loading and maximum weight bearing capacity. 6-Insulator...
