Parameters IBase, Ubase and SBase have been implemented as a
settings instead of a parameters, which means that if the values of the
parameters are changed there will be no restart of the application. As
restart is required to activate new parameters values, the IED must be
restarted in some way. Either manually or by changing some other
parameter at the same time.
The following general settings can be set for the Phase-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.
Xmax: Maximum value for analog signal X.
Xmin and Xmax values are directly set in applicable measuring unit, V,
A, and so on, for all measurement functions, except CVMMXN where
Xmin and Xmax values are set in % of the base quantity.
XZeroDb: Zero point clamping. A signal value less than XZeroDb is forced to zero.
XRepTyp: Reporting type. Cyclic (Cyclic), amplitude deadband (Dead band) or
integral deadband (Int deadband). The reporting interval is controlled by the
parameter XDbRepInt.
XDbRepInt: Reporting deadband setting. Cyclic reporting is the setting value and is
reporting interval in seconds. Amplitude deadband is the setting value in % of
measuring range. Integral deadband setting is the integral area, that is, measured value
in % of measuring range multiplied by the time between two measured values.
