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.
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
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).
XHiLim
: High limit. Set as % of
YBase
(Y is
SBase
for S,P,Q
UBase
for Voltage measurement and
IBase
for current measurement).
