Setting procedure on the IED

The parameters for breaker monitoring (SSCBR) can be set using the local HMI or
Protection and Control Manager (PCM600).
Common base IED values for primary current (IBase), primary voltage (UBase)
and primary power (SBase) are set in Global base values for settings function
GBASVAL.
GlobalBaseSel: It is used to select a GBASVAL function for reference of base
values.
Operation: On or Off.
OpenTimeCorr: Correction factor for circuit breaker opening travel time.
CloseTimeCorr: Correction factor for circuit breaker closing travel time.
tTrOpenAlm: Setting of alarm level for opening travel time.
tTrCloseAlm: Setting of alarm level for closing travel time.
OperAlmLevel: Alarm limit for number of mechanical operations.
OperLOLevel: Lockout limit for number of mechanical operations.
CurrExponent: Current exponent setting for energy calculation. It varies for
different types of circuit breakers. This factor ranges from 0.5 to 3.0.
AccStopCurr: RMS current setting below which calculation of energy
accumulation stops. It is given as a percentage of IBase.
ContTrCorr: Correction factor for time difference in auxiliary and main contacts'
opening time.
AlmAccCurrPwr: Setting of alarm level for accumulated energy.
LOAccCurrPwr: Lockout limit setting for accumulated energy.
SpChAlmTime: Time delay for spring charging time alarm.
tDGasPresAlm: Time delay for gas pressure alarm.
tDGasPresLO: Time delay for gas pressure lockout.
DirCoef: Directional coefficient for circuit breaker life calculation.
RatedOperCurr: Rated operating current of the circuit breaker.
RatedFltCurr: Rated fault current of the circuit breaker.
OperNoRated: Number of operations possible at rated current.
OperNoFault: Number of operations possible at rated fault current.
