Microprocessor-based Protection Relays

SYMAP®ProductOverviewSYMAP® is a flexible microprocessor-based digital protection and control device for use in low,medium,andhigh-voltagepowersystems.Becauseofitsintegratedprotectionfunctionsandhuman-machine interface capabilities, it is an efficient and cost-effective solution for all types ofswitchgears.With threepowerfulmicroprocessors, SYMAP®offers completeprotectionand controlfunctions for generators,motors (synchronous and asynchronous), transformers, power lines, anddistributions.Allprotectionfunctionscanbeactivatedsimultaneously,andtherearenolimitsinusingallofthematthesametime.WithSYMAP®,fivemainbreakercontrolscanbeactivatedwithallthenecessaryfunctions,suchasdisplay, control, and blocking, for optimal breaker management. A small integrated PLC allowsindividualinterlocksofcontrolcommands.Forflexibilityincommissioningandduringuse,bothdigitalandanalogoutputscanbeusedtoconnecttheSYMAP®controlunittomainswitchboardcontrols.Additionally, a variety of serial interfaces with different kinds of data protocols can be used forcommunicationbetweenSYMAP®unitsandthecentralcontrolsystem.Fordiagnosticsandmonitoring,SYMAP®hasthreemicroprocessorswhichsuperviseeachother,andprovidingawatchdogsystem.Importantfunctionsarelaidoutinadoubleredundancycombination,operatingindependentlywiththesecondprocessor.Connectedseparately,anoptionalunitforshortcircuitprotectionoperatesparalleltotheSYMAP®deviceandwilldosoevenifthepowersupplyfails.
