  • Page 8: General Overview

    7IRD terminal units can be applied individually or combined with other intelligent electronic devices (IEDs) to form an integrated system for protecting and controlling medium voltage lines, transformers, generators and feeders in general. This instruction manual covers the 7IRD-A, 7IRD-J and 7IRD-M, and particular characteristics are specified where are relevant. General Overview 7IRD terminal equipment provides two different subsystems: protection and control.

  • Page 9: Protection Subsystem Functions

    Non-Directional Overcurrent Protection 3-Phase and Ground Includes four non-directional overcurrent measuring units (three for Phase Overcurrent protection and one for Ground). On 7IRD-A and 7IRD-M models each unit is comprised of a time element and an instantaneous element, with additional temporization adjustable. On 7IRD- J model each unit is comprised of a time element and two instantaneous elements, with additional temporization adjustable.
