Mode : Selection of measured current and voltage. There are 9 different ways of calculating
monitored three-phase values depending on the available VT inputs connected to the IED. See
parameter group setting table.
k : Low pass filter coefficient for power measurement, V and I.
VMagCompY : Magnitude compensation to calibrate voltage measurements at Y% of Vn, where Y is
equal to 5, 30 or 100.
IMagCompY : Magnitude compensation to calibrate current measurements at Y% of In, where Y is
equal to 5, 30 or 100.
IAngCompY : Angle compensation to calibrate angle measurements at Y% of In, where Y is equal to
5, 30 or 100.
The following general settings can be set for the Phase-phase current measurement (CMMXU).
IMagCompY : Magnitude compensation to calibrate current measurements at Y% of In, where Y is
equal to 5, 30 or 100.
IAngCompY : Angle compensation to calibrate angle measurements at Y% of In, where Y is equal to
5, 30 or 100.
The following general settings can be set for the Phase-phase voltage measurement (VMMXU).
VMagCompY : Amplitude compensation to calibrate voltage measurements at Y% of Vn, where Y is
equal to 5, 30 or 100.
VAngCompY : Angle compensation to calibrate angle measurements at Y% of Vn, where Y is equal
to 5, 30 or 100.
The following general settings can be set for all monitored quantities included in the functions
(CVMMXN, CMMXU, VMMXU, CMSQI, VMSQI, VNMMXU) X in setting names below equals S, P, Q, PF,
V, I, F, IA,IB,IC, VA, VB, VCVAB, VBC, VCA, I1, I2, 3I0, V1, V2 or 3V0.
Xmin : Minimum value for analog signal X.
Xmax : Maximum value for analog signal X.
XZeroDb : Zero point clamping. A signal value less than XZeroDb is forced to zero.
XRepTyp : Reporting type. Cyclic ( Cyclic ), magnitude deadband ( Dead band ) or integral deadband
Int deadband ). The reporting interval is controlled by the parameter XDbRepInt .

Parameters
of a parameters, which means that if the values of the parameters are changed
there will be no restart of the application. As restart is required to activate new
parameters values, the IED must be restarted in some way. Either manually or by
changing some other parameter at the same time.
Xmin and Xmax values are directly set in applicable measuring unit, V, A, and so on,
for all measurement functions, except CVMMXN where
set in % of the base quantity.
