EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
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.
Extra High Voltage substation. It generally 132 kv or higher
Usually HV is 33KV and 66KV, EHV is 132KV, 220KV and 400KV and UHV is 800KV and 1200KV
LILO is Line In Line Out. If a new EHV substation is inserted between two existing substaions, the transmission line for new inserted EHV substation is called LILO i.e. Line In Line Out. When a transmission line is passing nearby to a substation or generation station to tap it, the system used is called LILO. While using this system , one bay is required for incomer and the other is outgoing. The power is drawn or added as per requirement. It may also be called Loop In Loop OutSP.

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
That's what they say so it is!
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 = 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.

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.
