Why earthing power transmission line?
It is necessary because lightning can destroy whole phase conductors. Lightning has energy of 1MHp. So much high energy if falls on transmission line will not even destroy it but all of the distribution systems too. The reason that lightning falls on tower is that it always chosses the shortest path.
What is LILO in electrical transmission?
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.
What is pg clamps in transmission line?
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
What is the line voltage of a 230000 kv transmission line?
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.
What is leakage current in underground transmission line?
The leakage current in underground transmission line are any two conductors separated by an insulating medium. It constitutes a condenser and a capacitor.
Why we can't send current or voltage without transmission line?
Well, there is no way of doing it without an overhead or underground transmission line.
Is underground transmission line is possible?
yes,ofcoarse, its in use in many places

How many underground stations does the Bakerloo Line Call At?
There are 15 Underground station at the Bakerloo line.
Why higher voltege required for long transmission line?
To (a) eliminate high voltage drops along the line, (b) to allow conductors of practical size to be used, and (c) to reduce line losses.
What is the color of the circle line in London underground?
On the London Underground map, the Circle Line is coloured yellow.
How do you change transmission line?
how to fix a transmission without taking it a part how to fix a transmission line
What underground line to get from euston to Victoria?
The Victoria Line.
What is line charging in transmission?
Transmission Line Charging To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
What are the components used for trnsmission lines?
There are no component is used in transmission line . the used things are- conductors for transmitting power to one place to another place. insulator for separate these conductors and some other basic things are required necessary for net of transmission line.
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
