DESCRIPTION
Neg Sequence
[Indexed String]
Setting that determines whether the directional function uses zero sequence or negative sequence voltage polarizing.
IN> VNpol Input 38 58 Derived
Derived
Setting determines which will be selected as the input source of polarizing voltage for directional decision, 'derived' or 'measured'.
IN> VNpol Set 38 59 1
From 0.5*V1 to 80*V1 in steps of 0.5*V1
[Courier Number (voltage)]
Setting for the minimum zero sequence voltage polarizing quantity for directional decision. Setting is visible only when ‘Zero Sequence’
polarization is set.
IN> V2pol Set 38 5A 1
From 0.5*V1 to 25*V1 in steps of 0.5*V1
[Courier Number (voltage)]
Setting for the minimum negative sequence voltage polarizing quantity for directional decision. Setting is visible only when ‘Negative
Sequence’ polarization is set.
IN> I2pol Set 38 5B 0.08
From 0.08*I1 to 1.0*I1 in steps of 0.01*I1
[Courier Number (current)]
Setting for the minimum negative sequence current polarizing quantity for directional decision. Setting is visible only when ‘Negative
Sequence’ polarization is set.

Default Curve 1
Default Curve 2
Default Curve 3
Default Curve 4
[Indexed String]
Setting to determine the type of reset/release characteristic of the user defined curves.
DEF REV Set 39 08 0.04
From 0.03*I1 to 1.0*I1 in steps of 0.01*I1
[Courier Number (current)]
Setting the reverse pickup current sensitivity for residual current (= 3.Io).
Virtual I Pol 39 09 Enabled
Enabled
To enable (activate) or disable (turn off) the Virtual Current Polarizing if it has been armed by the DEF Polarizing setting The setting is invisible
if ‘Neg. Sequence’ polarization is set.
