1. Description
Transformer protection IED RET650
RET650 provides fast and selectiveprotection, monitoring and control for alltypes of transformers, such as two and three-winding transformers, autotransformers,shunt reactors and step-up transformers inpower stations.
2. Application
RET650 provides fast and selectiveprotection, monitoring and control for two-and three-winding transformers,autotransformers, generator-transformer unitsand shunt reactors. The transformer IED isdesigned to operate correctly over a widefrequency range in order to accommodatepower system frequency variations duringdisturbances and generator start-up and shut-down.
A very fast differential protection function,with automatic CT ratio matching and vectorgroup compensation, makes this IED theideal solution even for the most demandingapplications. RET650 IED has very lowrequirements on the main CTs, nointerposing CTs are required. The differentialprotection function is provided with 2ndharmonic and wave-block restraint features toavoid tripping for magnetizing inrush, and5th harmonic restraint to avoid tripping foroverexcitation.
The differential function offers a highsensitivity for low-level internal faults.RET650 IED's unique and innovative sensitivedifferential protection feature, based on well-known theory of symmetrical componentsprovide best possible coverage for windinginternal turn-to-turn faults.
Low impedance restricted earth-faultprotection functions are available ascomplimentary sensitive and fast mainprotection against winding earth faults. Thisfunction includes a directional zero-sequencecurrent criterion for additional security.
Tripping from Pressure relief / Buchholz andtemperature devices can be done through theIED where pulsing, lock-out contact outputetc. is performed. The binary inputs areheavily stabilized against disturbance toprevent incorrect operations at e.g. dc systemcapacitive discharges or dc earth faults.
Versatile phase, earth, negative and zerosequence overcurrent functions, which can bemade directional, provide further alternativebackup protection. Thermal overload withtwo time-constants, volts per hertz, over/under voltage are also available.
Built-in disturbance and event recorderprovides valuable data to the user aboutstatus and operation for post-faultdisturbance analysis.
Breaker failure protection allow high speedback-up tripping of surrounding breakers.
Disturbance recording is available to allowindependent post-fault analysis after primarydisturbances.
Three packages has been defined forfollowing applications:
• Two winding transformer in singlebreaker arrangements (A01)
• Three winding transformer in singlebreaker arrangements (A05)
• Tap changer control (A07)
The packages are configured and ready fordirect use. Analog and tripping IO has beenpre-defined for basic use. Other signals needto be applied as required for each application.
The graphical configuration tool ensuressimple and fast testing and commissioning.

with or without on-load tap-changer as wellas for shunt reactors or and local feederswithin the station. An adaptive stabilizingfeature is included for heavy through-faults.
Stabilization is included for inrush currentsrespectively for overexcitation condition.Adaptive stabilization is also included forsystem recovery inrush and CT saturation forexternal faults. A fast high set unrestraineddifferential current protection is included forvery high speed tripping at high internal faultcurrents.
Innovative sensitive differential protectionfeature, based on the theory of symmetricalcomponents, offers best possible coverage forpower transformer windings turn-to-turnfaults.
Restricted earth fault protectionREFPDIF
Restricted earth-fault protection, lowimpedance function (REFPDIF) can be usedon all directly or low impedance earthedwindings. REFPDIF function can providehigher sensitivity (down to 5%) and higherspeed as it measures individually on eachwinding and thus do not need inrushstabilization.
The low impedance function is a percentagebiased function with an additional zerosequence current directional comparisoncriteria. This gives excellent sensitivity andstability for through faults. The functionallows use of different CT ratios andmagnetizing characteristics on the phase andneutral CT cores and mixing with otherfunctions and protection IEDs on the samecores.
5. Current protection
Instantaneous phase overcurrentprotection PHPIOC
The instantaneous three phase overcurrentfunction has a low transient overreach and
short tripping time to allow use as a high setshort-circuit protection function.
Four step phase overcurrentprotection OC4PTOC
The four step phase overcurrent function hasan inverse or definite time delay independentfor each step separately.
All IEC and ANSI time delayed characteristicsare available.
The directional function is voltage polarizedwith memory. The function can be set to bedirectional or non-directional independentlyfor each of the steps.
Instantaneous residual overcurrentprotection EFPIOC
The single input overcurrent function has alow transient overreach and short trippingtimes to allow use for instantaneous earthfault protection, with the reach limited to lessthan typical eighty percent of the transformerimpedance at minimum source impedance.The function can be configured to measurethe residual current from the three phasecurrent inputs or the current from a separatecurrent input.
Four step residual overcurrentprotection EF4PTOC
The four step residual overcurrent protection(EF4PTOC) has an setable inverse or definitetime delay independent for step 1 and 4separately. Step 2 and 3 are always definitetime delayed.
All IEC and ANSI time delayed characteristicsare available.
The directional function is voltage polarized,current polarized or dual polarized.
The protection can be set directional or non-directional independently for each of the steps.
A second harmonic blocking can be enabledindividually for each step.

ABB 13
Thermal overload protection, twotime constant TRPTTR
If the temperature of a power transformer/generator reaches very high values theequipment might be damaged. The insulationwithin the transformer/generator will haveforced ageing. As a consequence of this therisk of internal phase-to-phase or phase-to-earth faults will increase. High temperaturewill degrade the quality of the transformer/generator oil.
The thermal overload protection estimatesthe internal heat content of the transformer/generator (temperature) continuously. Thisestimation is made by using a thermal modelof the transformer/generator with two timeconstants, which is based on currentmeasurement.
Two warning levels are available. Thisenables actions in the power system to bedone before dangerous temperatures arereached. If the temperature continues toincrease to the trip value, the protectioninitiates trip of the protected transformer/generator.
Breaker failure protection CCRBRF
Breaker failure protection (CCRBRF) functionensures fast back-up tripping of surroundingbreakers in case of own breaker failure toopen. CCRBRF can be current based, contactbased, or adaptive combination betweenthese two principles.
A current check with extremely short resettime is used as a check criteria to achieve ahigh security against unnecessary operation.
A contact check criteria can be used wherethe fault current through the breaker is small.
Breaker failure protection (CCRBRF) functioncurrent criteria can be fulfilled by one or twophase currents, or one phase current plusresidual current. When those currents exceedthe user defined settings, the function isactivated. These conditions increase thesecurity of the back-up trip command.
CCRBRF function can be programmed to givea three-phase re-trip of the own breaker toavoid unnecessary tripping of surroundingbreakers at an incorrect initiation due tomistakes during testing.
Pole discordance protectionCCRPLD
Circuit breakers or disconnectors can due toelectrical or mechanical failures end up withthe different poles in different positions (close-open). This can cause negative and zerosequence currents which gives thermal stresson rotating machines and can causeunwanted operation of zero sequence ornegative sequence current functions.
Normally the own breaker is tripped tocorrect such a situation. If the situationpersists the surrounding breaker should betripped to clear the unsymmetrical loadsituation.
The pole discordance function operates basedon information from the circuit breaker logicwith additional criteria from unsymmetricalphase current when required.
Directional over/underpowerprotection GOPPDOP/GUPPDUP
The directional over-/under-power protection(GOPPDOP/GUPPDUP) can be usedwherever a high/low active, reactive orapparent power protection or alarming isrequired. The functions can alternatively beused to check the direction of active orreactive power flow in the power system.There are number of applications where suchfunctionality is needed. Some of them are:
• detection of reversed active power flow• detection of high reactive power flow
Each function has two steps with definitetime delay. Reset times for every step can beset as well.
Negative sequence basedovercurrent function DNSPTOC
Negative sequence based overcurrentfunction (DNSPTOC) is typically used as
Transformer protection RET650 1MRK 504 110-BEN AProduct version: 1.0 Issued: February 2010
14 ABB
sensitive earth-fault protection of powerlines, where incorrect zero sequencepolarization may result from mutualinduction between two or more parallel lines.
Additionally, it is used in applications onunderground cables, where zero sequenceimpedance depends on the fault currentreturn paths, but the cable negative sequenceimpedance is practically constant.
DNSPTOC protects against all unbalancefaults including phase-to-phase faults. Alwaysremember to set the minimum pickup currentof the function above natural systemunbalance level.
6. Voltage protection
Two step undervoltage protectionUV2PTUV
Undervoltages can occur in the power systemduring faults or abnormal conditions. Twostep undervoltage protection (UV2PTUV)function can be used to open circuit breakersto prepare for system restoration at poweroutages or as long-time delayed back-up toprimary protection.
UV2PTUV has two voltage steps, each withinverse or definite time delay.
Two step overvoltage protectionOV2PTOV
Overvoltages may occur in the power systemduring abnormal conditions, such as, suddenpower loss, tap changer regulating failures,open line ends on long lines.
Two step overvoltage protection (OV2PTOV)can be used as open line end detector,normally then combined with directionalreactive over-power function or as systemvoltage supervision, normally then givingalarm only or switching in reactors or switchout capacitor banks to control the voltage.
OV2PTOV has two voltage steps, where step1 is setable as inverse or definite timedelayed. Step 2 is always definite time delayed.
OV2PTOV has an extremely high reset ratioto allow setting close to system service voltage.
Two step residual overvoltageprotection ROV2PTOV
Residual voltages may occur in the powersystem during earth-faults.
Two step residual overvoltage protection(ROV2PTOV) calculates the residual voltagefrom the three-phase voltage inputtransformers or from a single-phase voltageinput transformer fed from an open delta orneutral point voltage transformer.
ROV2PTOV has two voltage steps, wherestep 1 is setable as inverse or definite timedelayed. Step 2 is always definite time delayed.
Overexcitation protectionOEXPVPH
When the laminated core of a powertransformer or generator is subjected to amagnetic flux density beyond its designlimits, stray flux will flow into non-laminatedcomponents not designed to carry flux andcause eddy currents to flow. The eddycurrents can cause excessive heating andsevere damage to insulation and adjacentparts in a relatively short time. The functionhas settable inverse operating curve andindependent alarm stage.
7. Frequency protection
Under frequency protection SAPTUF
Under frequency occurs as a result of lack ofgeneration in the network.
Under frequency protection (SAPTUF) is usedfor load shedding systems, remedial actionschemes, gas turbine start-up and so on.
SAPTUF is provided with an under voltageblocking.
Transformer protection RET650 1MRK 504 110-BEN AProduct version: 1.0 Issued: February 2010
ABB 15
Over frequency protection SAPTOF
Over frequency protection (SAPTOF) functionis applicable in all situations, where reliabledetection of high fundamental power systemfrequency is needed.
Over frequency occurs at sudden load dropsor shunt faults in the power network. Closeto the generating plant, generator governorproblems can also cause over frequency.
SAPTOF is used mainly for generationshedding and remedial action schemes. It isalso used as a frequency stage initiating loadrestoring.
SAPTOF is provided with an under voltageblocking.
Rate-of-change frequencyprotection SAPFRC
Rate-of-change frequency protection(SAPFRC) function gives an early indicationof a main disturbance in the system. It can beused for generation shedding, load shedding,remedial action schemes etc. SAPFRC candiscriminate between positive or negativechange of frequency.
8. Secondary systemsupervision
Breaker close/trip circuitmonitoring TCSSCBR
The trip circuit supervision function TCSSCBRis designed to supervise the control circuit ofthe circuit breaker. The invalidity of a controlcircuit is detected by using a dedicatedoutput contact that contains the supervisionfunctionality.
