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.

Is earthing required in Underground transmission line?
Earthing is always required. It is necessary so that a fault or overvoltage, such as caused by a lightning strike, may be conducted to earth (ground), either dissipating the energy and/or tripping the protective device.
What is uncompensated power transmission line?

What is surge impedance in power systems?
Actually surge impedance is present in a transmission line due to the capacitance of transmission line. Now this capacitor attends the reactive power of the transmission line to energise its magnetic flux. now due to the flux the impedance will increase and the power is reactive too. due to the impedance loss is more.
What is the difference between chemical earthing and conventional earthing?
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
What is applications of earthing?
An earthing system can be defined as the electrical potential of the conductors relative to the EarthÍs conductive system. The choice of earthing method can influence the safety and electromagnetic compatibility of the power supply, and regulations can vary considerably among countries.
Is earthing required in Underground transmission line?
Earthing is always required. It is necessary so that a fault or overvoltage, such as caused by a lightning strike, may be conducted to earth (ground), either dissipating the energy and/or tripping the protective device.
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
Why does a 2003 impala transmission loses power?
TRANSMISSION LINE LOSSES
What is the formula for calculating power loss in transmission lines?
The formula for calculating power loss in transmission lines is Ploss I2 R, where Ploss is the power loss, I is the current flowing through the transmission line, and R is the resistance of the transmission line.

What if you touch a 25000 volts power line earthing ourselves?
In all probability you will almost instantly turn into a smoking lump of cooked meat.
What is the formula for calculating power loss in a transmission line?
The formula for calculating power loss in a transmission line is Ploss I2 R, where Ploss is the power loss in watts, I is the current flowing through the line in amperes, and R is the resistance of the line in ohms.
How do you transmit ac power flow in HVDC transmission line?
You don't! That's the whole point of a d.c. transmission line.

Which line requires compensation?
Basically an AC transmission line require compensation in terms of reactive power. To push the active power across a transmission line certain amount of reactive power is necessary. In AC transmission line reactive power is generated and consumed. Generator is responsible for the production of reactive and active power both. Than this reactive power is consumed by the load and transmission line. Additional reactive power s supplied by the capacitor. This extra power supplied by the capacitor is termed as reactive power compensation. Requirement of this reactive power is there because reactive power is necessary to maintain the voltage stability.
How many max transmission voltage in India?
There are three types of transmission lines of India given follows ---- 1-long transmission line( which is used grid to power suppliers plant ) 2-medium transmission line ( which is used power supplier plant to the industry ) 3- short transmission line ( which is used transformer to the consumers )
