AnomAlert*
Motor Anomaly
Detector
Introduction
Bently Nevada’s AnomAlert* Motor Anomaly Detector solution
provides a low cost innovative AC motor and load anomaly
detection system that compliments predictive maintenance
programs. A very simple user interface, in conjunction
with intelligent, on-board model-based condition analysis
provides valuable and timely anomaly detection capabilities
for most induction, synchronous and variable speed motordriven equipment. Automated fault analysis using the motor
as a mechanical load condition sensor for both the motor and
driven load is achieved using CT/CS1 and PT2 instrumentation
generally already on the motor.
The AnomAlert system is simple to install, requires little
user intervention in operation, and combines low start-up
costs with the significant benefits of anomaly detection as
a complementary component of a predictive maintenance
program. Since it generally doesn’t require any sensor
installation on the motor or associated load, AnomAlert*
is especially attractive for inaccessible equipment and
is applicable to most types of motor driven pumps,
compressors, and similar loads.
Benefits
The Anomalert Motor Condition Monitoring solution:
• Installs very easily, typically less than one hour per motor set,
assuming that CTs and PTs are installed by a certified high
voltage engineer, in conjunction with plant electrical support.
• Requires very little panel space and volume, and has a
simple user display.
• Utilizes existing sensing instrumentation when available, or
recommended CT/CSs and PTs to match the motor type.
• Performs advanced mathematical modeling to provide
automated notifications of many electrical and
mechanical faults.
• Increases machine availability by improving maintenance
planning and reducing unexpected outages.
• Is easy to use, requires minimal training and very basic
support to get started.
Continuous access to motor health information
The Bently Nevada AnomAlert Motor Anomaly Detector
solution enables plant operators or technicians to spend more
time managing assets based on information from process
data and reliability information, instead of spending time
making data collection rounds. This leverages your gives your
plant personnel a key advantage by minimizing the amount
of time that the maintenance staff needs to spend gathering
information and attempting to identify where a issue is
occurring. It enables the engineering team to immediately
initiate corrective actions by knowing where best to focus their
efforts before more serious problems develop.
Features
• Detects electrical and mechanical faults without additional
instrumentation.
• Requires no intervention while continuously monitoring the
motor and driven load.
• Provides clear local and remote indication of the type and
severity of the problem and the recommended action
when a fault is detected.
• Sends an email, detailing potential problems to
maintenance staff, avoiding the need for frequent review
of data displays.
• Requests condition monitoring when needed.
• Easy to configure
• Low install cost
• Requires fewer technologies to support condition
monitoring.
• Reduces manning requirements needed to provide same
condition monitoring support level.
• Enables Remote Diagnostic Service capability.
• No long cable runs or specialized sensors that require
maintenance.
• Continuous monitoring reduces periodic portable data
collection when no problems exist.
• • No calibration required
• Identifies opportunities to reduce energy consumption.
Applications
• Roller element bearing motors and driven loads for the
following example applications:
— Cryogenic motor-pump,
— Submerged
— Nuclear
— Offshore
— Remote
— Hazardous
— Difficult access,
— Fin fans
— Harsh Duty
Summary
With a minimum hardware and services investment, overall
plant reliability can be improved by applying Bently Nevada’s
AnomAlert* Motor Anomaly Detector solutions on your midlevel critical motor driven loads.
