Equipment failure can happen at any time. Fortunately,
Electrical Reliability Services' proactive technologies and services can
help determine when a failure or outage may occur. A
well-constructed predictive maintenance program can help maximize
your electrical asset's productivity as well as eliminate catastrophic
equipment failures, saving you both time and money.
A predictive maintenance program is a window into the future of
your equipment's performance. By performing predictive
maintenance tests, we can identify when a failure is likely to occur
so you can plan an outage instead of dealing with an unexpected
failure. This information is essential in making the best use
of your maintenance dollars. We have many predictive
maintenance solutions, utilizing today's technologies, and can help
you prepare the best plan for your unique situation. Benefits
of predictive maintenance include:
- Elimination
of unplanned outages
- Risk
Assessment / Management
- Optimized
capital expenditures
- Improved
system reliability
- Increased
availability due to greater reliability of the equipment
- Planned
maintenance vs. Reactive
- Reduced
cost of maintenance and
labor
- Assurance
of initial equipment installation
- Reduced
likelihood of a catastrophic failure
- Improved worker safety
- Improved
operating efficiency
- Reduced
capital costs by extending the life of plant assets
and increasing availability
- Deferred
or avoided capital costs for added capacity
-
Minimized
scheduled outages – Extending time between outages
Depending on your need, Emerson's
portfolio
of services enables you to select a single technology or an entire
Predictive Maintenance program to meet your specific
requirements. We offer the following solutions:

Partial
Discharge Testing & Monitoring Solutions
Partial
discharges are small electrical sparks that occur within the
insulation of electrical assets.
Each discrete partial discharge is a result of the
electrical breakdown of an air pocket within the insulation. These
imperfections create voltage stresses, resulting in eventual
insulation failure.
Data obtained through Partial Discharge testing and monitoring can provide
critical information regarding the quality of insulation and its
impact on the overall equipment health.
Because PD activity is often present well in advance of
insulation failure, it is possible to observe its development over
time in order to assist asset managers with strategic decisions
regarding the repair or replacement of the equipment—prioritizing
capital and MRO investments before an unexpected outage occurs.
Partial
discharge testing results are used to help predict future performance
and reliability of critical assets including:
- Cables,
splices, and terminations
- Power
Transformers, Bushings, and Capacitors
- Switchgear
- Circuit
Breakers
- Motors
& Generators
Emerson’s
integrated Partial Discharge Testing and Monitoring Solutions include
both online and offline testing, and periodic and continuous
monitoring of your electrical assets.
Depending on your specific operating requirements and
application, Emerson can customize a program that best fits your needs
and can include the following:

Infrared/Thermal
Imaging
Infrared or Thermal
Imaging testing detects heat buildup in electrical equipment caused by
corrosion, loose connections or overload. Infrared testing
can detect these abnormal thermal increases in electrical and
mechanical equipment before an unplanned outage occurs.
Equipment and components routinely tested include:
- Substation
Transformers
- Capacitor Banks
- Switches
- Fuses
- Circuit Breakers
- Busbars
- Cable Splicing
- Motors
- Motor Control
Centers (MCC)
Infrared Inspections are performed while your system is
energized and operating avoiding any operational disruption.
There is no physical contact with the equipment but the equipment
enclosure must be open allowing there to be a direct line of
sight. The equipment must also carry a load current during
the inspection.
Early detection from infrared testing can avoid unnecessary
operational, safety, and financial losses. Other benefits
include:
- Enables planned maintenance rather than emergency repairs
- Conducted while equipment is energized and operating,
avoiding disruption of operations
- Eliminates potentially catastrophic losses due to equipment
failures from electrical fires or other serious results when
problems are not found with traditional maintenance methods
- Extends equipment lifecycle through early diagnosis and
subsequent repair
- Promotes safety in the workplace since personnel are not
exposed to faulty equipment
- Reduces equipment failures, protecting your capital
equipment investment

Oil
Analysis
Oil
analysis involves capturing and examining routine
samples of oil for particulates and contaminates that include wear.
Electrical Reliability Services' oil analysis service
offers a full spectrum of oil analysis techniques and tests to
ensure your organization receives the best possible information with
regards to your electrical equipment. Combined with our
other monitoring services, oil analysis data can be used to easily
diagnose possible impending equipment failures as well as possible
lubrication needs.

Ultrasonics
When problems occur in medium and high voltage
electrical equipment, it will produce sound waves that can be
detected by using Ultrasonic testing. Performed without
disrupting plant or facility operations, Ultrasonic testing is a
non-destructive, non-invasive predictive maintenance tool.
Because it maintains insulation integrity, it is commonly
employed in applications such as cable terminations, switchgear,
busbars, or transformers.
