4.2.4.5.4 Analog inputs
Analog inputs are used for fundamental measurement
of currents and voltages used in protecting switchgear.
Analog inputs use currents and voltages from current
and voltage instrument transformers installed in
switchgear. The following parameters of submenu may
differ for different device types.

Rated nominal current of the object [IL Nominal]
Rated nominal current of the object I
n_obj
(outgoing
feeder, motor, etc.). The value is later used on
calculation and display of specified value in p.u. units.
The parameter defines 1 p.u. of protected element.
Example:
Calculation of motor phase currents based on nominal
primary current of the motor I
n_obj
:
Device measure current I
S
= 0.7 A
That would mean that motor phase currents I
n_obj
are
currently at 80 % of its nominal value.

4.2.4.5.5 Analog outputs DC
Analog output presents information about fundamental
measurement and calculations of the device in form of
output current. The output current ranges maximally
from 0 mA to 20 mA. Output current peak to peak value
