EPCsEPCsFaster project deliveryReduce material (cabling)Reduced risk on cableengineering
High degree ofstandardizationpre-engineered buildingblocks, e.g. panels, kiosks
Easier handling of latechangesas all communication isdigital IEC61850
IET600
UtilitiesUtilitiesIncreased safety bydigitizing all signals right attheir source reduces the riskof electrical hazards
Integration of NCITs byadherence to standards andby that further increase safety& availability
Outage time reductionfaster installation throughpre-tested process bussystems
Cost effective maintenancemore supervision anddiagnostics, reduced spareparts
Lower requirements onCTs/VTs by reducing burdenfrom cabling and minimizingNo of circuits

Contro&Protection IED
§ “Digital” Switchgears for up to24kV
§ Non-conventional current andvoltage sensors
§ IEDs exchange GOOSE and IEC61850-9-2 sampled voltagevalues on station bus within theswitchgear
§ IEDs can act as publisher andreceiver of sampled values
§ Only voltage values areexchanged
ABB’s process bus product portfolioNCIT for metal-clad switchgear
§ Redundant, combined current andvoltage sensor(Rogowski coils, capacitive dividers)
§ Redundant sensor electronics can bereplaced during operation, nocalibration necessary
§ Configurable current ratings enablefuture adaptation of CT ratios
§ Metering, protection and controlaccuracy in a single device
§ Merging unit with large number of portsenables efficient system design

§ IEC 61850-9-2LE
§ Redundancy as option
§ Meets modern performancerequirements in terms of accuracy(0.2S; 5TPE)
§ Being filled with N2 at <0.5 rel bar, it isintrinsically safe and environmentallyfriendly
§ It does not require modification insubstation layout, where conventionalCTs are installed

Redundant system setup
§ The FOCS system comprises of redundantthree-phase light source and signalprocessing.
§ Redundant fiber optics integrated to theDCB pole.
§ A primary sensor head with redundant fiberoptic coils per phase of DCB.
§ “Plug & Play” solution. Fully “hotswappable” redundant system.
Measurement Platform
§ Electro optic module and measurementcoil delivering sampled values according toIEC 61850 9-2 LE
SAM600 process bus IO system
Modular IO system§ One hardware module per primary object philosophy
§ Conventional current or voltage transformers§ Circuit breakers, disconnectors, earthing switches (version
2.0)§ Time synchronization
§ Modules can be chained into a system in order to optimally adaptto different application types – “the sum is more than its parts”
Compact, optimized form factor§ DIN-rail mountable for fast installation and replacement§ Indoor - bay cubicles for retrofit applications§ Outdoor - marshalling kiosks, VT terminal boxes
Termination of primary cabling on SAM600 module§ Customizable terminals, usage of standard cabling, emergency
control§ One module terminating process and auxiliary signals (e.g., VT
fuse failure) – eliminate cross-wiring
Digitizing primary signals made easy
