Bently Nevada AnomAlert Specifications

AnomAlert* Motor Anomaly Detector

Bently Nevada* Asset Condition Monitoring

Description

AnomAlert Motor Anomaly Detector continuously identifies existing and
developing faults on electric motors and their driven equipment. AnomAlert
utilizes an intelligent, model-based approach to provide anomaly detection by
measuring the current and voltage signals from the electrical supply to the
motor. It is permanently mounted, generally in the motor control center and is
applicable to 3-phase AC, induction or synchronous, fixed or variable speed
motors. Accompanying AnomAlert Software is used to view the data.

AnomAlert provides both mechanical (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. In addition, it can detect changes in the load the motor is experiencing
due to anomalies in the driven equipment or process such as cavitations or
plugged filters and screens. Since it doesn't require any sensor installation on the
motor itself or associated load, AnomAlert is especially attractive for inaccessible
driven equipment and is applicable to most types of pumps, compressors, and
similar loads.

Each motor requires one AnomAlert and it can be configured entirely from the
front panel. Additionally, each AnomAlert includes the AnomAlert Software
necessary to obtain and display data in real-time from the device, to configure
the performance of the device, and to save and subsequently retrieve data for
display from its database. Networking protocols enable monitoring of motors
and processes on remote machines using TCP/IP protocols over the Ethernet.
