OverviewTheMINII,amemberoftheMIIfamilyofprotectionrelays,isamicroprocessorbased relay that provides ground directional protection on distributed networks at any voltage level andbackup/auxiliary ground directionalprotectionfortransformers,generatorsandmotors.Additionallyitcanbeusedtocreateaseparatedirectionalcomparisongroundschemeinpilotchannelsusedfordistancerelaying.TheMINIIrelaycanbeusedinsystemswheretheneutralisrigidlyconnectedtotheground,wheretheconnectionisdonethrougharesistororaPetersencoil,andalsowhere theneutral is isolated fromtheground(ungroundedsystems).Twomodelsareavailable:Models‘E’and‘S’.Basicprotectionfeaturesforthemodel‘E’ (neutral rigidly or through resistor connected to ground) include grounddirectional time delayed overcurrentandground instantaneousovercurrent(two levelseachHisetandLoset).Eachunitcanbeselectedtobedirectionalornot.Forthemodel‘S’(isolatedgroundor connection through Petersen Coil) theMIN IIhas two independentdirectionalunits.Each protection element can beselectively enabled either via the frontpanel or via communication. Flexiblesettings, selectableANSIor IECcurves,plus the choice of a user configurableovercurrent curve enable accuratecoordinationwithotherdevices.TheMIN II has two fixed digital inputsandsixfixeddigitaloutputs.Anoptionis

Anoption isprovidedallowing fourof theseLEDstobeuserconfigurable.The frontpanelalso featuresa5-buttonkeypad and a 16x2 LCD display that providesaneasytouseuserinterface.The front keypad allows the user to setthe baud rate and relay address forcommunication.AfrontRS232andarearRS485communicationportareprovidedfor computer access using ModBus®RTU protocol. The rear RS485 can be convertedtoanRS232orfiberopticport(plasticorglassfiberoptics)bymeansofusing an external converter, such asGEMultilinDAC300orF485.Windows®basedEnerVistaTM software is provided free ofchargewiththerelaytoallowsetupandconfigurationofMIFIIunits.Computer access allows setting and configuration (inputs, outputs, LEDs andconfigurablelogic)oftheunits,displayofmeteringinformationandrealtimestatusoftheunit .Anoptionisprovidedallowingthe display of event records and an oscillographyrecordforthelastfault .

Ground Time Overcurrent
TheMINIIprovidesgroundtimeovercurrentprotectionthatcanbesetfrom0.1to2.4timesIn.Threedifferentcurvetypescanbeselected:ANSI,IEC/BS142andoneuserconfigurable.Thisallowstheselectionoftheoptimumcurveforcoordinationwith
fuses, feeders, motor transformers etc.ANSIandIECcurvesinclude:definitetime,normalinverse,veryinverse,andextremelyinverse. For each curve, different time multipliersmaybeset.CurveTypes:
• ANSI IEC/BS142
• Normalinverse IECA
• Veryinverse IECB
• Extremelyinverse IECC
• Definitetime
Ground Instantaneous Overcurrent units
The MIN II includes two separatelyadjustable ground instantaneousovercurrent units. Each one can beindependentlyenabled.Settingsallowthepickup setpoint tobe set from0.1 to30timesInandatimedelayfrom0to600.00secondstobeset.

The relay operation is based on thepresenceofthiscapacitivecurrentplusthedetectionofanovervoltagecondition.
Peterson Coil Directional Control
TheMINIIprovidesdirectionalprotectionfor systems where the connectionto the ground is done through aPetersen coil. This scheme is knownas ground resonant circuit or groundfault neutralizer. The relay operationis based on a real power directionalprotection unit , being intrinsically a ground directional function polarized byzerosequencevoltage.The torqueangledefinestheoperationzoneandthethreemagnitudes (residual current , residual voltageandrealpower)definethepickupvalue.

Event Recording
Eventsconsistofabroadrangeofchangeof state occurrences, including pickups,trips, contact operations, alarms andself test status. The MIN II stores up to24 events time tagged to the nearest millisecond.Thisprovidestheinformationneededtodeterminesequenceofeventswhich facilitates diagnosis of relayoperation. Each event is individuallymaskableinordertoavoidthegenerationof undesired events, and includes thevalues of currents and voltages, andstatusofalltheprotectionelementsatthemomentoftheevent.
Oscillography
MIN II captures current waveforms anddigital channels at 8 samples per cycle.Oneoscillographyrecordwithamaximumlengthof24cycles is stored inmemory.Oscillographyistriggeredeitherbyinternalsignalsoranexternalcontact.TheMINIIcanbeaccessedwithaPCusingtheMIIEnerVistaTMSetupSoftwareviatheRS232communicationportlocatedintherelayfrontpanel.Iftherelaywasfurnishedwiththeappropriateoption,useEnerVistaTM to display last fault information such aseventreportsandanoscillographyrecords.TheMINIIhasadrawoutconstruction in1/4ofa19’’rackcase.
Configurable I/O and LEDs
