been selected as well. Best match for current and voltage
measurement can be managed by selecting two AIM2 cards for
the relay. This combination offers 12 current and 8 voltage
channels to be freely allocated for the relay functionalities. The
OLTC control function requires information on the tap-
changer’s actual position. To be able to provide this
information, the relay is equipped with an RTD card which can
measure the OLTC position either as a resistance value or as an
mA signal.
