AnomAlert Generator Anomaly Detector
Datasheet

Bently Nevada Machinery Condition Monitoring288496 Rev. F

Description
AnomAlert Generator_Anomaly_Detector continuously
identifies existing and developing faults on three-phase AC
generators and their prime movers, effectively using thegenerator itself as a sophisticated transducer. AnomAlert
Generator_Anomaly_Detector utilizes an intelligent, modelbased approach to provide anomaly detection by simply
measuring the generator current and voltage. It ispermanently mounted, generally in the generator control
center.
AnomAlert Generator_Anomaly_Detector provides bothmechanical (unbalance, misalignment, roller bearings, etc.)
and electrical (loose windings, short circuits, etc.) anomaly
detection as well as electrical parameters such as voltage
and current imbalances and power factor.
Each generator requires one AnomAlert Anomaly Detector,
and it can be configured entirely from the front panel.
Additionally, the AnomAlert Enterprise Software is available
that obtains and displays real-time data from the device. It
configures the performance of the device, and stores datathat can be retrieved for display from its database.
A System 1 Software Extender is also available that adds
generators to your overall machinery enterprise hierarchy. It
enables viewing real-time data and generating sophisticatedalerts and alarms and produces intelligent advisories thatdeliver Actionable Information to designated users.
