Infrared Thermography is
an integral part of any Preventative
Maintenance and Loss Control Program. Many
problems in electrical systems are caused by
abnormal heating associated with high
resistance or excessive current flow.
Infrared Thermography allows us to see these
invisible thermal patterns before damage or
failure occurs. Infrared surveys are useful
in any application where a temperature
difference can be used to identify problem
areas.

Infrared Thermography
locates problems typically not found during
shutdowns. It also finds overloaded, loose,
and corroded connections. Some of the many
benefits to having your equipment scanned
are:
• Reduces costly downtime
• Saves time and money on emergency repairs
• Prevents equipment failures
• Identifies and prioritize areas needing
preventative maintenance
• Improves electrical and mechanical
efficiency
• Avoids disruption of services by using
noninvasive technology
• Reduces emergency calls for maintenance
crews
• Identifies fire hazards
What is Infrared
Thermography
An infrared is a non-contact noninvasive
means of scanning and data collecting.
During a scan no equipment will need to be
shut down. Which means no downtime for your
equipment. Infrared imaging reveals
electrical problems based on subtle
temperature variations caused by loose
connections, phase imbalance, circuit
overloading and other “invisible” problems
that can lead to equipment damage or
breakdowns.
Infrared thermography is an integral part of
any Preventative maintenance and Loss
Control Program. Utilizing Thermal Scanning
on at least an annual basis for electrical
and mechanical systems can improve the
reliability of these systems and increase
profitability.
Finding and fixing a poor
electrical connection before a component
fails can save you the much greater costs
associated with manufacturing downtime,
production losses, power outages, fires and
catastrophic failures.
“Planned maintenance of
plant and equipment that is designed to
improve equipment life and avoid any
unplanned maintenance activity.”
Temperature differences,
even though small, can be serious, depending
on the equipment, the load or voltage it is
carrying, and the need for continuity of
operation. Therefore, the ultimate decision
to repair them must be made by the plant
personnel. The problems found with infrared
fall into two general categories: contact
surface problems and overload imbalance
problems.
An Overload or Imbalance
problem is when heat is produced by high
current flow and/or high resistance through
a portion of the circuit or a phase of the
circuit. These are generally associated with
under size conductors, overload phase
imbalances.
A Contact Surface problem
is when heat is produced by current flow
through a single point of electrical contact
with high resistance.
Most materials expand as
they are heated and contract if they are
cooled. This is known as Thermal Expansion.
Thus, their length is a function of
temperature. If the length of an object is L
and the temperature changes by a different
amount dT, then the differential change in
the length is dL is given by: dL=xL dT
Preventative
Maintenance
• Helps to improve power quality
• Helps stop wasting energy due to heat
loss.
• Reduces down time
• Increases safety
Transformers
A transformer is typically a very expensive
piece of equipment, some worth thousands of
dollars or more. They are also very
sensitive damage by over heating. A
transformer designed to last 20 years at
normal temperature may only last a few years
if it overheats.
Switchgear maintenance
Switchgear Maintenance is a part of any
maintenance program (both preventative and
predictive) that will help you operate your
facility’s system at its peak performance.
Regular switchgear maintenance, inspection
and testing will help you mitigate any
problems and provide you with a reliable
system that is essential to the efficient
operation of your facility.
Harmonics, which are caused primarily by
nonlinear loads, can cause a variety of
problems to power systems serving computer
systems such as waveform distortion,
improper voltage readings and especially
overheating in the system neutral conductor.
How is your Neutral?
In our growing use of electronics,
fluorescent lighting and computer put a
large demand on the neutral. Loose,
undersized, or over loaded neutrals can
bring the work place to a stop. When the
neutral fails it could cause fire,
electrical shock, major equipment loss and
down time.
Bad Neutral Our Service & Your Business
