Field Parameters
ECT sec
This parameter defines
the secondary nominal
current of the connected
earth current transformer.
If the earth current is
done via the Holmgreen
connection, the primary
value of the phase
current transformer must
be entered here.

Earth fault protection with
directional feature
depends also on the
correct wiring of the earth
current transformer. An
incorrect polarity/wiring
can be corrected by
means of the settings
"0°" or "180°". The
operator has the
possibility of turning the
current vector by 180
degrees (change of sign)
without modification of
the wiring. This means,
that – in terms of figures -
the determined current
indicator was turned by
180° by the device.

IL1, IL2, IL3 Cutoff Level The Current shown in the
Display or within the PC
Software will be
