This article presents advanced relay protection systems that incorporate Rogowski Coil current sensors and multifunction relays. Rogowski coils are accurate and do not saturate, making it possible to set protection levels to lower fault current thresholds (increased sensitivity of the scheme) while preserving high stability of the scheme for through faults. This reduces the stress on the protected equipment during faults. Even though Rogowski Coils are low power sensors, the protection system is immune to external electromagnetic fields. The schemes are simple, user friendly and require less wiring and space than conventional solutions. More
