INGEPAC™ EF LD is a phase-segregated line differential protection relay, designed for main protection of power lines and underground cables on all voltage levels.
It also includes a complete distance protection scheme of 5 zones, in order to increase the security in case of failure of the communication channel.
INGEPAC™ EF LD supports dual CT inputs to monitor both breakers individually, making it the best solution suitable for multibreaker schemes, such us breaker and a half or ring applications.
