By just seeing a transmission tower, how can we knew the
voltage it carries..?[110kv, 220kv, 400kv...]???

Answer Posted / noufal p

The no of insulators for a particular HT voltage can be found out using the following method,

No of Insulators = ((Phase Voltage )/ 11KV )+ 2 );

because, insulators are calculated for phase voltages, one disc insulator can carry almost 11KV. One or two extra insulators can be provided to reduce the voltage stress of each insulator
