Abstract
This paper presents Rogowski coil current sensor performance characteristics for advanced relay protection systems. Rogowski coils are specially designed to be immune to external electromagnetic fields. They are accurate and do not saturate. Principles of applications for phasor-based and traveling wave-based relaying schemes are presented. A companion paper [Kojovic, 2008] describes advanced protection schemes that incorporate Rogowski coils and multifunction relays.
