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.
MeasurementType: This default setting is DFT, which gives fundamental frequency amplitude and angle.
It can be set as RMS, if true RMS value over one cycle is required.
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.
MeasurementType: This default setting is DFT, which gives fundamental frequency amplitude and angle.
It can be set as RMS, if true RMS value over one cycle is required.
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.
Observe the related zero point clamping settings in Setting group N for CVMMXN (VGenZeroDb and
IGenZeroDb). If measured value is below VGenZeroDb and/or IGenZeroDb calculated S, P, Q and PF
will be zero and these settings will override XZeroDb.
XRepTyp: Reporting type. Cyclic (Cyclic), magnitude deadband (Dead band), integral deadband (Int
deadband) or Deadband and xx se cyclic (xx: 5 sec, 30 sec, 1 min). The reporting interval is controlled by
the parameter XDbRepInt.
XDbRepInt: This setting handles all the reporting types. If setting is deadband in XRepTyp, XDbRepInt
defines the deadband in m% of the measuring range. For cyclic reporting type (XRepTyp : cyclic), the
setting value reporting interval is in seconds. Magnitude deadband is the setting value in m% of
measuring range. Integral deadband setting is the integral area, that is, measured value in m% of
measuring range multiplied by the time between two measured values.
XHiHiLim: High-high limit. Set as % of YBase (Y is SBase for S,P,Q UBase for Voltage measurement and
IBase for current measurement).
XHiLim: High limit. Set as % of YBase (Y is SBase for S,P,Q UBase for Voltage measurement and IBase
for current measurement).
XLowLim: Low limit. Set as % of YBase (Y is SBase for S,P,Q UBase for Voltage measurement and
IBase for current measurement).
