Application manual
VGenZeroDb: Minimum level of voltage in % of VBase, used as indication of zero
voltage (zero point clamping). If measured value is below VGenZeroDb calculated S, P,
Q and PF will be zero.
IGenZeroDb: Minimum level of current in % of IBase, used as indication of zero
current (zero point clamping). If measured value is below IGenZeroDb calculated S, P,
Q and PF will be zero.
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 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 set directly in applicable measuring unit.
This forms the minimum limit of the range.
Xmax: Maximum value for analog signal X. This forms the maximum limit of the
range.
XZeroDb: Zero point clamping. A signal value less than XZeroDb is forced to zero.
