Transmission Line Protection Using Digital Technology

First Edition

Transmission lines at different voltage levels are traditionally protected by distance protection relays. They have been serving for many decades as a reliable protection tool. However, when we move to the extra high voltage level and start looking at the challenges that lines with complex configuration, such as double circuit series compensated transmission lines, present, we can see that distance protection faces some challenges for cross-country faults, high-resistance faults, open conductor, etc. More
