Monitoring
UAmpCompY : Amplitude compensation to calibrate voltage measurements at Y% of Ur, where
Y is equal to 5, 30 or 100.
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 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
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 : 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
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
IBase for current measurement).
