Overview

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.


Functions

  • Line differential protection (instantaneous and restrained)
  • Suitable for double lines and lines with capacitive voltage transformers
  • Up to 2 communication ports (FO single-mode, C37.94 or G703), for 2 or 3 end zones
  • Teleprotection and blocking schemes: DTT, PUTT, POTT, etc.
  • IEC 61850 native platform
  • PRP, HSR and link failover redundancy
  • Automatisms, logics under IEC 61131-3 standard
  • Captures analog measurements using Sampled Values (SV) protocol, through IEC 61850-9-2 or IEC 61869-9 standards
  • Cybersecurity features: sFTP, HTTPs, firewall, audit log, password accessing
  • Slave protocol: IEC 61850, DNP 3.0, IEC 870-5-103, PROCOME
  • Synchronization sources: IEEE 1588, SNTP or IRIG-B
