Function must be
1.000 Typically no scaling is required
180.0 Typically no angle compensation is required.
However here the required direction of P & Q
measurement is towards busbar (Not per IED
internal default direction). Therefore angle
compensation have to be used in order to get
measurements in aliment with the required
direction.
L1L2 Only UL1L2 phase-to-phase voltage is
available
0.00 Typically no additional filtering is required
25 Set minimum voltage level to 25%
3 Set minimum current level to 3%
35.00 Set LV side rated phase-to-phase voltage
495 Set transformer LV winding rated current
31.5 Set based on rated power
