Setting procedure on the IED

The parameters for breaker monitoring (SSCBR) can be set via Protection and Control Manager
(PCM600).
Common base IED values for primary current (
power (
GlobalBaseSel : It is used to select a GBASVAL function for reference of base values.
PhSel : It is used to select different phase values.
IBase : Base phase current in primary A. This current is used as reference for current settings.
InitCounterVal : Initial value for number of operations
InitAccCurrPwr : Initial value for accumulated I^CurrExponent integr over CB open travel time
value.
InitInactDays : Initial value for inactive days.
InactiveAlHrs : Alarm time for inactive days counter in hours.
InitCBRemLife : Initial value for remaining life estimates.
InactiveAlDays : Alarm level for inactive days counter.
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.

Since there is no current measurement in SAM600-IO, evaluation of the
following parameters are not possible in the circuit breaker condition
monitoring function (SSCBR):
• Circuit breaker status
• Remaining life of the circuit breaker
• Contact erosion estimation
• Circuit breaker contact travel time
Ensure that OPENPOS, CLOSEPOS, INVDPOS, CBLIFEAL, IPOWALPH,
IPOWLOPH, TRVTOPAL and TRVTCLAL signals are not used in SAM600–IO.
