7IRD
represents a family of integrateable microprocessor-based terminal units for
line/machine protection.
The
7IRD
digital design is based on a powerful microprocessor and organized into models to
provide protection, control and metering functions. The protection provided by the standard
models includes: Complete protection of a given position; Monitoring and Annunciation
(remote and optionally local) of any device associated to that position; Analog values metering
(Current, Voltage, Power, …); Capture of information associated to that position, via digital
inputs; Possibility to perform programmable control functions and local interlockings.
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.
1.1
General Overview
7IRD
terminal equipment provides two different subsystems: protection and control. Both are
inter-communicated so that they can cooperate by information exchange, but always
maintaining separate identities for any kind of action. Main features that can be detailed are:
Devices include independent power supplies for protection and control functions.
Available communication ports are common for protection and control subsystems.
Digital input and output contacts are separated for protection and control functions.
Analog inputs measurement is performed by the protection subsystem thought
independent circuits. There is an option that allows that metering is performed by a
dedicated and specific module.
