How to calculate required distance between arcing horn on insulator (Line side to tower side) of 220 KV transmission line for line having altitude of 1500 m to 2000 m above mean sea level.
Does this distance depend on elevation of line ? Does it depend on rated impulse withstand voltage of insulator ?
In India its value is 2130 mm considering normal altitude . Is this value is similar to other country practice ?
Thanks
