Description

Controller 1MRK002814-AC

Controller 1MRK002814-AC

Optionally available voltage and frequency protection functions enable to include voltage release criterion for busbar protection or to integrate independent over-, under-voltage protection for the bus in the busbar protection IED.

Optionally available over-current, thermal overload and capacitor bank protection functions open possibilities to integrate protection of shunt reactors and shunt capacitor banks into the busbar protection IED.

It is normal practice to have just one busbar protection IED per busbar.

Nevertheless some utilities do apply two independent busbar protection IEDs per zone of protection. This IED fits both solutions. A simplified bus differential protection for multi-phase faults and earth faults can be obtained by using a single, one-phase IED with external auxiliary summation current transformers.

Forcing of binary inputs and outputs is a convenient way to test wiring in substations as well as testing configuration logic in theIEDs. Basically it means that all binary inputs and outputs on the
IED I/O modules (BOM, BIM, IOM & SOM) can be forced to
arbitrary values.
