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.
Parameters IBase, Ubase and SBase have been implemented as a settings
instead 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.
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.
Xmin and Xmax values are directly set in applicable measuring unit, V, A,
and so on, for all measurement functions, except CVMMXN where Xmin
and Xmax values are set in % of the base quantity.
XZeroDb: Zero point clamping. A signal value less than XZeroDb is forced to zero.
