Abstract :
This paper describes a directional comparison protection unit that can be applied to power lines, buses or transformers either as main protection or backup for the differential protection. Without settings, this unit provides excellent dependability and security. The protection algorithms have been tested with a RTDS system simulating very adverse internal and external faults.
