INGEPAC™ EF LD
Line Differential Control and Protective Relay
INGEPAC™ EF LD is a phase-segregated line differential protection relay, designed for the main protection of power lines and underground cables on all voltage levels.
It also includes a complete distance protection scheme of 5 zones, 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 as breaker and a half or ring applications.
