The selection of the reference used in the relay's per-unit system
scaling. Either the set phase current CT primary or the protected
object's nominal current.
Phase CT
primary
A
1…25000 0.001 100
The rated primary current of the current transformer.
Phase CT
secondary
A
0.2…10
0.001 5
The rated secondary current of the current transformer.
Nominal current
In
A
1…25000 0.001 100
The nominal current of the protected object. This setting is only
visible if the option "Object In p.u." has been selected in the "Scale
measurement to In" setting.
IL1 Polarity
-
0: -
1: Invert
-
0: -
The selection of the first current measurement channel's (IL1)
polarity (direction). The default setting is for the positive current to
flow from connector 1 to connector 2, with the secondary currents'
starpoint pointing towards the line.
IL2 Polarity
-
0: -
1: Invert
-
0: -
The selection of the second current measurement channel's (IL2)
polarity (direction). The default setting is for the positive current to
flow from connector 3 to connector 4, with the secondary currents'
starpoint pointing towards the line.
IL3 Polarity
-
0: -
1: Invert
-
0: -
The selection of the third current measurement channel's (IL3)
polarity (direction). The default setting is for the positive current to
flow from connector 5 to connector 6, with the secondary currents'
starpoint pointing towards the line.
CT scaling
factor P/S
-
-
-
-
A relay feedback value; the calculated scaling factor that is the ratio
between the primary current and the secondary current.
CT scaling
factor NOM
-
-
-
-
A relay feedback value; the calculated scaling factor that is the ratio
between the set primary current and the set nominal current. This
parameter is only visible if the option "Object In p.u." has been
selected in the "Scale measurement to In" setting.
Ipu scaling
primary
-
-
-
-
A relay feedback value; the scaling factor for the primary current's
per-unit value.
Ipu scaling
secondary
-
-
-
-
A relay feedback value; the scaling factor for the secondary current's
per-unit value.
