Earth overcurrent protection elements take into account
this parameter for direction decisions. You have to
ensure, that this parameter is set to "Measured" only if
the ground current is fed to the fourth measuring input of
the current measuring card.

Ground MTA
Ground Maximum Torque Angle: Angle between chosen
operating quantity and chosen reference quantity in case
of a ground fault. This angle is needed to determine the
ground fault direction in case of a short circuit.
Depending on the selected ground direction option,
different MTA values are used: IR 3V0, IX 3V0 : Ground
MTA; IR Neg, IX Neg : 90° + Phase MTA; IR IPol : 0°; IR
Dual : 0° (if I2 and V2 available) or Ground MTA; IX
Dual : 90° + Phase MTA (if I2 and V2 available) or
Ground MTA.
