What is transmission line protection?

Transmission Line Protection Definition: Transmission line protection is a set of strategies used to detect and isolate faults on power lines, ensuring system stability and reducing damage. Selective Tripping: This method ensures that only the breaker nearest to the fault trips, preserving system integrity and limiting the impact of faults.

How to protect transmission lines?

There are various aspects to consider when protecting transmission lines. The following are the factors that have an effect on protection. Overloading the system and lightning. These elements play a major part in the protection of transmission towers & electrical cables.

What makes a good electric protection system?

The electric protection system must be able to detect all faults on the protected line. The protection system must be able to clear faults very quickly, (i.e. in less than 1 s) before the power system goes unstable. The protection system must be dependable, and must be capable of clearing faults when any single piece of equipment has failed.

How transmission line protection is different from transformer protection?

These above mentioned requirements cause protection of transmission line much different from protection of transformer and other equipment of power systems.
