Advantages of High Transmission Voltage

Hi Hello friends, today we talked about the advantages and disadvantages of more voltage in the transmission line.

Before we talk about this, let’s see how much electricity is generated in our power plant.

Power generation in India is generated within 6.6 KV or 11KV or( 6600 volts or 11000 volts.)

After generating electricity, we install a step-up transformer there

This step-up transformer does the work of converting low voltage to high voltage.

Then we send this high voltage from one place to another with the help of the transmission line.

Advantage of High Transmission Voltage

The following are some of the advantages of having a high voltage transmission line.

1. Voltage Drop.

2. Transmission wire cost reduced.

3. Reduce Power loss.

1. Voltage Drop:

The first advantage of giving more voltage in the transmission line is the voltage drop.

What is the voltage drop?

We can easily understand it this way. We sent as much voltage from one place but we are not able to get the full voltage from another place.

This means that some of our voltages have decreased in the middle, so this is called voltage drop.

2. Transmission wire cost reduced:

Increasing the voltage reduces the cost of building our transmission line.

This is because, as we all know, if the voltage is increased, the current decreases.

Similarly, when we increase the voltage of the transmission line, the current of our line decreases.

And we can use as thin a wire as the current passes through the wire

In the same way, we increase the voltage and decrease the current so that we have to thin the wire of the transmission line.

And by doing so we get a significant reduction in the cost of buying wire.

3. Reduce Power loss:

When we increase the voltage, it reduces a lot of losses in our electrical.

And we all know that if the losses are less then our electrical efficiency increases. Which is very beneficial for our electrical equipment.

The Disadvantage of High Transmission Voltage

High Transmission Voltage Some of the disadvantages are as follows.

1. Insulator size increase

2. Switch Gear Cost increase 

3. Transmission Tower Height Increase

4. Corona loss

1. Insulator size increase:

Insulator

Here we are talking about an insulator that creates a gap between the electric pole and the wire.

Guys, as we assume in an easy way, we have to insert a disk for 11000 volts. This means that the higher the voltage, the more disk we have to insert.

2. Switch Gear Cost increase:

Here we have to install a system breaker with more voltage, then we have to install a circuit breaker with more voltage.

And we always have to keep in mind that the higher the voltage of a circuit breaker or any device, the more sensitive and expensive it is.

3. Transmission tower height increase:

Transmission Tower height increase

The third disadvantage of making more friends is the cost of building the transmission tower.

When we increase the voltage of the transmission line, it becomes necessary to increase the height of the electrical tower along with it.

If this is not done then phase to earth fault occurs.

That is why the gap between the transmission wire and the ground has to be widened with the addition of voltage.

Due to which the cost of our transmission line increases.

4. Corona loss:

Corona Effect

Corona Loss This is the last point and much more important, you must tell it in the interview with Electrical.

Whenever we increase the voltage, the corona loss in our transmission line also starts increasing.
