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).
XLowLowLim: Low-low limit. Set as % of YBase (Y is SBase for S,P,Q UBase for Voltage
measurement and IBase for current measurement).
XLimHyst: Hysteresis value in % of range and is common for all limits.
All phase angles are presented in relation to defined reference channel. The parameter
PhaseAngleRef defines the reference, see Section
Calibration curves
It is possible to calibrate the functions (CVMMXN, CMMXU, VMMXU and
VNMMXU) to get class 0.5 presentations of currents, voltages and powers. This is
accomplished by magnitude and angle compensation at 5, 30 and 100% of rated current
and voltage. The compensation curve will have the characteristic for magnitude and angle
compensation of currents as shown in figure
as reference channel and compared with the curve for calculation of factors. The factors
will then be used for all related channels.
