Monitoring
IBase : Base phase current in primary A. This current is used as reference for current settings.
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
AccStopCurr : RMS current setting below which calculation of energy accumulation stops. It is
given as a percentage of
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.
CBLifeAlmLevel : Alarm level for circuit breaker remaining life.
AccSelCal : Selection between the method of calculation of accumulated energy.
OperTimeDelay : Time delay between change of status of trip output and start of main contact
separation.
