AnomAlert* Motor Anomaly Detector Fact SheetIntroductionGE Energy’s Bently Nevada* AnomAlert* MotorAnomaly Detector solution provides a low costinnovative AC motor and load anomaly detectionsystem that compliments predictive maintenanceprograms. A very simple user interface, inconjunction with intelligent, on-board model-basedcondition analysis provides valuable and timelyanomaly detection capabilities for most induction,synchronous and variable speed motor-drivenequipment. Automated fault analysis using themotor as a mechanical load condition sensor forboth the motor and driven load is achieved usingCT/CS1 and PT2 instrumentation generally alreadyon the motor.

The AnomAlert* system is simple to install, requireslittle user intervention in operation, and combineslow start-up costs with the significant benefits ofanomaly detection as a complementarycomponent of a predictive maintenance program.Since it generally doesn't require any sensorinstallation on the motor or associated load,AnomAlert* is especially attractive for inaccessibleequipment and is applicable to most types ofmotor driven pumps, compressors, and similarloads.

BenefitsThe Anomalert* Motor Condition Monitoringsolution:• Installs very easily, typically less than one hour

per motor set, assuming that CTs and PTs areinstalled by a certified high voltage engineer, inconjunction with plant electrical support.

• Requires very little panel space and volume,and has a simple user display.

• Utilizes existing sensing instrumentation whenavailable, or recommended CT/CSs and PTs tomatch the motor type.

• Performs advanced mathematical modeling toprovide automated notifications of manyelectrical and mechanical faults.

• Increases machine availability by improvingmaintenance planning and reducingunexpected outages.

• Is easy to use, requires minimal training andvery basic support to get started.

Continuous Access to Motor Health Information

The Bently Nevada* AnomAlert* Motor AnomalyDetector solution enables plant operators ortechnicians to spend more time managing assetsbased on information from process data andreliability information, instead of spending timemaking data collection rounds. This leverages yourgives your plant personnel a key advantage byminimizing the amount of time that themaintenance staff needs to spend gatheringinformation and attempting to identify where aissue is occurring. It enables the engineering teamto immediately initiate corrective actions byknowing where best to focus their efforts beforemore serious problems develop.

AnomAlert* Motor Anomaly Detector Fact SheetFeatures

• Detects electrical and mechanical faultswithout additional instrumentation.

• Requires no intervention while continuouslymonitoring the motor and driven load.

• Provides clear local and remote indication ofthe type and severity of the problem and therecommended action when a fault isdetected.

• Sends an email, detailing potential problemsto maintenance staff, avoiding the need forfrequent review of data displays.

• Requests condition monitoring whenneeded.

• Easy to configure• Low install cost• Requires fewer technologies to support

condition monitoring.• Reduces manning requirements needed to

provide same condition monitoring supportlevel.

• Enables Remote Diagnostic Servicecapability.

• No long cable runs or specialized sensorsthat require maintenance.

• Continuous monitoring reduces periodicportable data collection when no problemsexist.

• No calibration required• Identifies opportunities to reduce energy

consumption.
