Application manual
IAngCompY: Angle compensation to calibrate angle measurements at Y% of Ir,
where Y is equal to 5, 30 or 100.
The following general settings can be set for the Phase current measurement
(CMMXU).
IAmpCompY: Amplitude compensation to calibrate current measurements at Y% of
Ir, where Y is equal to 5, 30 or 100.
IAngCompY: Angle compensation to calibrate angle measurements at Y% of Ir,
where Y is equal to 5, 30 or 100.
The following general settings can be set for the Phase-phase voltage
measurement (VMMXU).
UAmpCompY: Amplitude compensation to calibrate voltage measurements at Y%
of Ur, where Y is equal to 5, 30 or 100.
UAngCompY: Angle compensation to calibrate angle measurements at Y% of Ur,
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, U, I, F, IL1-3, UL1-3UL12-31, I1, I2,
3I0, U1, U2 or 3U0.
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
(UGenZeroDb and IGenZeroDb). If measured value is below UGenZeroDb and/or
IGenZeroDb calculated S, P, Q and PF will be zero and these settings will override
XZeroDb.
XRepTyp: Reporting type. Cyclic (Cyclic), amplitude 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. Amplitude 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).
