INGEPAC™ EF equipment consists of digital multifunction control and protection devices with numerical technology based on IEC 61850 communication protocol.  They simultaneously incorporate many protection functions chosen from a set of options into one single unit, providing a solution which is adapted to each user's needs.
There are 6 subfamilies, depending on the characteristics required:
⦁ INGEPAC EF LD: Line differential protection and control 
⦁ INGEPAC EF ZT:  Distance protection and control relay
⦁ INGEPAC EF TD: Transformer protection and control relay
⦁ INGEPAC EF CD: Control and measurement device
⦁ INGEPAC EF CB: Capacitor bank protection and control relay
⦁ INGEPAC EF MD:  Multifunctional protection and control relay
Some exclusive features of EF relays are :
⦁ Based on IEC 61850 complete data model
⦁ Protection and control (BCU) in the same device
⦁ Graphical local interface (Graphical 5̎ display)
⦁ Powerful logic capabilities based on IEC 61131-3 (Ladder)
⦁ High precision measurement (144 Sample/Cycle)
⦁ Front USB and LAN ports
