Improved Safety During Infrared Inspections
of Electrical Equipment
There are 5-10 serious arc flash incidents
every day in North America. These incidents result
in approximately 2000 workers being treated in burn
centers annually. It is estimated that arc flash incidents
cost organizations hundreds of millions of dollars.
In response to this problem, NFPA (National Fire Protection
Agency) and OSHA (Occupational Safety and Health Administration)
have created guidelines for operating around energized
electrical circuits and following proper safety practices.
Updated just this year, NFPA 70E now includes specific
references to thermal imaging and makes a number of
important clarifications on electrical safety.

Secrets to a Successful Thermal Imaging
Based Building Energy Audit
Today, thermal imaging has become an
important inspection tool for identifying heat loss,
energy leaks and underlying factors that are critical
to the energy usage in a commercial building or home.
This white paper reviews fundamentals
of an energy audit, the different types of infrared
cameras that can be used in energy audits, the use
of a blower door to improve infrared inspections, thermal
behavior of windows and reporting.

Testing Building Envelope Systems
Using Infrared Thermal Imaging
The structures we live and work in are
susceptible to quality and performance problems during
construction and maintenance that can impact performance
and may, in some cases, render them dangerous. Regardless
of the building type involved, infrared thermography
can provide remarkable, nondestructive information
about construction details and building performance.
This paper discusses the numerous applications
for thermal imaging technology currently being used
to inspect building envelopes. These include validation
of structural details, verification of energy performance
(conduction and air leakage), location of moisture
intrusion, and the identification of structural and
system degradation of roofs and facades. Examples will
be given for each application and the basic conditions
required will be discussed.

Locating Levels
in Tanks and Silos Using Infrared Thermal Imaging
Infrared thermal imaging is a powerful
tool for locating and verifying levels in tanks and
silos. Other level indication instruments are often
not sufficiently reliable in many situations, or positive
verification of the instrumentation readings is required.
When properly used, thermal imaging can reveal not
only the liquid/gas interface, but also sludge buildup
and floating materials such as waxes and foams. Similar
techniques can be used to locate levels and bridging
problems in silos containing fluidized solids.
This paper discusses the parameters and
limitations that must be addressed, shows techniques
that can be employed, and illustrates the discussions
with numerous thermal images.

Guidelines for Performing Infrared
Inspections of Motor Control Centers
Whether it's your first infrared inspection
or you're a veteran with hundreds of surveys under
your belt, it is important to realize that in order
to successfully identify and analyze thermal anomalies,
it is beneficial to understand the operation of the
equipment under inspection.
Download this white paper to learn about
the recommended guidelines for inspecting the motor
control center (MCC). The paper describes how to identify
key components and potential problem areas and illustrates
both common and not-so-common thermal anomalies.

Understanding Infrared Camera Thermal
Image Quality
You’ve no doubt purchased a digital
camera sometime over the past few years to replace
your old film camera. Often thermal camera brochures
offer list specification that you, as a user, may never
be able to confirm or even understand. This paper’s
objective is to help you simplify your understanding
of how image quality is determined.
Covered are three topics that directly
influence thermal image quality: pixel resolution,
thermal sensitivity, and non-uniformity correction.
A number of related topics are discussed as well.

Integrating Thermography with
Your CMMS-EAM System
More and more companies are investing
in CMMS systems to organize the complex task of managing
capital equipment and facility infrastructure whether
it is process or production equipment or building systems
like HVAC and computers. If maintenance practices and
investments are to really pay off, the integration
of the two tools is necessary.
This paper discusses techniques useful
to integrate CMMS data into portable thermal imaging
cameras and to update machinery health databases with
field data. Specific examples of doing this in practice
are provided.

Advances in Auto Infrared
Report Generation
In-camera field data collection is more
productive than written or voice recorded notes. The
advantages of route-based infrared inspection are described
permitting improvements in predictive maintenance programs.
In-camera data logging ensures that established naming
conventions are used and consistently followed improving
the efficacy of training efforts for multiple operators
and overall performance. The impact on staff hours
is discussed as well as program costs and ROI.
|
Periodic Route Based Infrared Inspections
Infrared thermographic inspection is
an established PdM inspection modality. Recent advances
in infrared camera platforms have created a new class
of infrared imaging instrument which incorporates pen-based
computing and application-specific software into a
powerful thermal inspection data logger with many traits
similar to mature vibration data collection systems.
The potential impact of this integration
on productivity, thermography program ROI, training
and integration of thermal inspection data with CMMS
systems is described and presented.

Safer Thermography: Understanding
and Reducing Arc Flash
A PowerPoint presentation that presents
an overview of parts of NFPA 70E with a specific discussion
of arc flash includes the causes and effects, risk
hazard analysis, shock and flash protection boundaries
as well as hazard and risk classifications. In addition,
there is a discussion of the challenges for IR Thermography
including the use of viewing windows for cabinet inspection,
the basic premise of selection guidelines and implementation
ideas.

NFPA 70E, Arc Flash Best Practices
Estimates indicate that 10-15 serious
arc-flash incidents; those that result in burn injuries
requiring treatment in a burn center, occur each day
in the U.S., so it is not surprising that awareness
of the hazards associated with arc flash continues
to grow. Concerns about operator safety are causing
inspectors of high voltage switchgear to adopt new
practices and new equipment.
We will examine the impact of new safety
practices and how infrared transparent windows can
be used to mitigate some of the risks of arc flash.
In this regard, considerations are given to safe and
efficient thermography practices.

Update on NFPA-70E and Impact on
Thermographers
There continues to be a great deal of
activity surrounding the update to NFPA 70E scheduled
to be published in October 2008. For the proposed 2008
edition of NFPA 70, National Electrical Code® (NEC®),
the Technical Correlating Committee (TCC) received
3,668 proposals and 3,206 comments during the revision
cycle. For those of us involved in working with energized
electrical circuits the outcome of the new standards
will likely impact how we do our job. The goal is to
increase safety through well thought through practices.

Guide
to Analyzing and Selecting
Infrared Cameras
The best way to begin comparing different
thermal imaging products is to design a matrix that
captures the essence of all the important requirements
for your application. By evaluating the relevance of
each item in the matrix, you can develop an easy way
to compare different products when many features have
a different impact on your evaluation. Without prior
experience, you may not be aware of certain issues that
may be important for your application (like NFPA 70E
arc flash safety compliance). Consequently, reviewing
this matrix as a guide will facilitate your product
evaluation.
