We see about Transmission line . What all the major fault occurs in transmission line.
In that I have taken only 3 example now.
Those are fault caused by natural , animals and human accident or human error.
If fault come on the transmission line then how to protect transmission line.
For any problem on Transmission line will cause blackout for full area.
To avoid that
This are the some of the protection used in transmission line there are.
1. Overcurrent fault
2. Earthfault.
3.Voltage and frequency protection.
4.Directional over current
5.Rev power.
6.Line differential.
7.Distance protection.
here i have show why we use distance protection for the line in easy way to understand.
