phase non-directional overcurrent protection, three-phase under and overvoltage
protection. The IED also incorporates a thermal overload protection function,
which supervises the thermal stress of the transformer windings to prevent
premature aging of the winding's insulation.
The RTD/mA input module is optional in the standard configuration. When using
the RTD/mA input module it is possible to have the tap changer position indication
as an mA signal, ambient temperature of the power transformer can be used in
thermal protection and the multi-purpose protection functions are available. The
multi-purpose protection function enables protection based on analog values from
the IEDs RTD/mA input module, or from other IEDs using analog horizontal
GOOSE messaging.
The IED with a standard configuration is delivered from the factory with default
settings and parameters. The end-user flexibility for incoming, outgoing and
internal signal designation within the IED enables this configuration to be further
adapted to different primary circuit layouts and the related functionality needs by
modifying the internal functionality using PCM600.
