Setting procedure on the IED
GUID-4E895FEA-74BF-4B11-A239-0574F8FF5188 v4
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.
