it depands on switching overvoltage or lightening overvoltage.
EHV - EXTRA HIGH VOLTAGE - STARTING 500 KILOVOLTS IN UP (500,000 VOLTS)
220 KV lines used in Kerala have a capacity of 880 Amps
Carry electrical power over extremely long distanceswith minimal I2*R losses. The higher the line voltage the lower the current the line has to carry to transmit the power from source to load.
Depending on the size of the transformer, it can be protected by fuses, thermal elements, or by a full relay protection package, which could include overcurrent relays, differential relays, and distance relays.

The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.

EHV = Extra High Voltage. To quote from the Wikipedia article (see link) "...this refers to equipment designed for more than 345,000 volts between conductors." Put simply - EHV transmission is the 'national grid' power system.

MAT-VE-AY-EHV
The twin moose type of conductor has by far the greatest diameter of any conductor. This allows it to carry more voltage than other types without melting or shorting. Therefore, it is the approved type of conductor for extra high voltage lines.
Carry electrical power over extremely long distanceswith minimal I2*R losses. The higher the line voltage the lower the current the line has to carry to transmit the power from source to load.
