Multiple Options

Several options for protection andcommunications are provided to matchbasictohighendapplicationrequirements.

Protection & ControlThe 339 motor protection system isdesigned to protect and manage smallto medium sized AC motors and drivenequipment . Flexible and powerful, the339providesadvancedmotorprotection,controlandmonitoringinoneintegrated,economical draw-out design. The 339contains a full range of self containedprotection and control elements asdetailed in theFunctionalBlockDiagramandFeaturestable.

Motor Thermal Model

To provide optimal protection andmaximum runtime, the 339 MotorProtectionSystememploysGE’sIndustryleading advanced Thermal Model,consistingofsixkeyelements:

• OverloadCurves

• UnbalanceBiasing

• Hot/ColdSafeStallRatio

• MotorCoolingTimeConstants

• ThermalInhibitandEmergencyRestart

• RTDBiasing

FlexCurves

Asmoothcustomoverloadcurveiscreatedusing FlexCurves. These curves can beused to protect motors with differentrotordamageandstatordamagecurves,allowingtotalmotordesigncapacitywithcompleteprotection.

Enhanced Diagnostics

Preventative Maintenance

The339allowsusertotrackrelayexposureto extreme environmental conditions bymonitoring and alarming at high or lowtemperatures. This data allows users toproactivelyscheduleregularmaintenanceworkandupgradeactivities.

Failure Alarm

The 339 detects and alarms oncommunication port and IRIG-B failures.The 339 also enables users to analyzesystem performance via diagnosticsinformation such as event records,oscillography,etc.Itissuesdetailedmotorhealthreportsandalarmswhenthresholdsareexceeded.

Cost Effective

Robust Design

The 339 is subjected to AcceleratedLife Testing (ALT) to validate accuraterelay functions under specified normalconditions.Thedeviceisfurthertestedfordurability throughHigh Accelerated LifeTesting (HALT), undergoing stress testingforextremeoperatingconditions.

Reduced Life Cycle Cost

The 339 is designed to reduce totalinstallation and life cycle cost formotorprotection. The draw out constructionof the device reduces downtime duringmaintenance and decreases extrawiring needed for relay testing andcommissioning.

Over/Under Voltage Protection

Overvoltage / Undervoltage protectionfeatures can cause a trip or generatean alarm when the voltage exceeds aspecified voltage setting for a specifiedtime.

Frequency Protection

The 339 offers overfrequency andunderfrequency protection elementsthat provide the ability to detect whenthe motor is operating at off-nominalfrequencieswhichcancausedamagetotheprocess.Insuchcases,theprotectionelementscantripthemotoroff-lineorcanbeusedtosignaltoupstreamprotectionand control devices to implement load-sheddingschemes.

Unbalance (Negative Sequence) Biasing

Negativesequencecurrent,whichcausesadditionalrotorheating,isnotaccountedfor in the thermal limit curves providedbythemanufacturer. The339measurescurrentunbalanceasaratioofnegativetopositivesequencecurrent.Thethermalmodel is then biased to reflect theadditionalrotorheating.

RTD Biasing

The Thermal Model relies solely onmeasured current to determinemotor heating, assuming an ambienttemperature of 40°C and normalmotorcooling. The actualmotor temperaturewill increase due to abnormally highambient temperatures or if the motorcoolingsystemshavefailed.

There are four main menus labeled Actual Values, Quick Setup, Setpoints, and Maintenance. Pressing the MENU key followed by the MESSAGE key scrolls through the four Main Menu Headers.

The ten button keypad allows users easy access to relay configuration and information.

IN SERVICE: This indicator will be on continuously lit if the relay is functioning normally and no major self-test errors have been detected.

TROUBLE: Trouble indicator LED will be AMBER if there is a problem with the relay or if relay is not programmed.

LOCKOUT: Lockout initiates when a lockout trip is active.

RUNNING: Indicates that the motor is running in normal operationSTOPPED: Indicates that the motor is stoppedSTARTING: Indicates that the motor is in the starting process

TRIP: Indicates that the relay has tripped the motor offline based on predefined programmed conditions.

ALARM: Indicates that the motor is currently operating in an alarm condition and may proceed to a trip condition if not addressed.

MAINTENANCE: Environmental alarms such as ambient temperature alarm, coil monitor or trip counter.
