Protection and ControlTheB30BusDifferentialSystemprovides,secure, subcycle low impedance busprotection for a single busbar with upto six feeders. The B30 is ideally suitedin applications where high impedanceschemes were typically used. Overallsystem costs can be reduced with theB30,sincethereisnoneedfordedicated,or interposing, CTs. TheB30 comeswithadvanced features, such as breakerfailure, CT trouble detection, under-voltage supervision, and dynamic busreplica.With itsextremeflexibility,whichincludesaCTratiomismatchofupto32:1between terminals, the B30 is the idealsolutioninawidevarietyofbusdifferentialapplications.
PartoftheUniversalRelayfamily,theB30comeswithavarietyofversatilefeaturestruly integrating protection, monitoring,metering, communicationand control inoneeasy-to-usedevice.TheUniversalRelayfamilyoffershigherdegreeofmodularityin its design and functionality providingsuperior performance in protection andcontrolmeetingthetoughestrequirementsofthemarketplace.
Bus Differential Protection
TheB30isbasedonacentralizedphase-segregatedarchitecturethatdoesnotrelyon extensive communications betweenIEDs,anapproach that increasesoverallreliability.
The B30 provides fast and secure lowimpedancebusprotectionwithsub-cycletrippingtimesaveraging0.75cycles.The
primaryprotectionisbasedondifferentialand directional protection principles,and uses a dedicated CT saturationmechanism for additional through-faultstability. This mechanism is capable ofdetectingsaturationofCTsasquicklyastwo milliseconds into an external fault .Theoverallsystemcostscanbereducedwith the B30 since there is no need fordedicated,orinterposing,externalCTs.
Dynamic Bus replica
TheB30providesadynamicbus replicafor differential protection. Built-inprogrammable logic removes the needforexternalauxiliaryrelays,andprovidestheability to includeorexcludecurrentsdynamicallyfromthedifferentialzone.ThisallowstheB30tofollowtheactualbusbarconfigurationwithnoexternal switching
ofCTcircuitsrequired.TheB30alsoavoidsblindandovertrippingspotsinsimplebusconfigurations.Reliabilityisincreasedandcosts reduced by eliminating auxiliaryrelays thatwouldotherwisebeused forswitchingphysicalcurrents.Theabilitytomonitorauxiliaryswitchesandacontactdiscrepancyalarmalsoprovidesincreasedsecurity.
Breaker Failure Protection
Three-polebreakerfailure(BF)protectionisavailable.TheB30systemprovidesforupto6BFelementsthatcanrespondtocurrents and/or auxiliary contacts. Thecurrent supervision provides fast resettime and separate settings for low-setandhi-setare implemented. TheBFcanbe initiated internally from the busbar

Built-in advanced Disturbance recording
The bus differential element picks up due to heavy CT saturation
The CT Saturation flag is set safely before the pickup flag
The directional flag is not set
The element does not maloperate
Despite heavy CT saturation the external fault is seen in the opposite direction
The bus differential element picks up
The CT Saturation flag is not set - no directional decision required
The directional flag is set
The element operates in 10 ms
All the fault currents are seen in one direction
The built-in advanced disturbance recording function allows users to view the COMTRADE files and trouble shoot bus fault . The internal operation of the B30 elements, logic, and outputs can be monitored in real time to simplify commissioning and troubleshooting procedures. Two cases are shown here:
External Fault: Even with heavy CT saturation and with only 1 msec of saturation free current B30 is stable for through faults. See the Directional Comparison element output, which adds additional security to the bus differential functionInternal Fault: For internal fault the CT saturation flag is not set and the directional element output is safely ignored resulting in an operating time of less than 10 msec.
