12.4 Interlocking (3)
12.4.1 Introduction
The interlocking functionality blocks the possibility to operate high-voltage switching
devices, for instance when a disconnector is under load, in order to prevent material
damage and/or accidental human injury.
Each control IED has interlocking functions for different switchyard arrangements,
each handling the interlocking of one bay. The interlocking functionality in each IED is
not dependent on any central function. For the station-wide interlocking, the IEDs
communicate via the station bus or by using hard wired binary inputs/outputs.
The interlocking conditions depend on the circuit configuration and status of the
system at any given time.
