A
Frontline troubleshooting
and predictive maintenance
In these applications, a member
of the facility’s maintenance team
responds to failures that may result in
downtime.
When the facility is down it is
not generating revenue, so there is
extreme urgency to get these prob-
lems identified so operations can be
restored as quickly as possible. With
equipment down, the maintenance
tech wants to see information about
the problem right on the screen of
the tool—as opposed to recording
it and then analyzing the data later
with a PC.
Symptoms include:
• Overheating transformers
• Overheating motors
• Reduced operating life of motors
and transformers
• Control system problems
(PLCs tripping)
• Nuisance tripping of circuit
breakers
B
Load studies
Before the installation of new
equipment or major distribution
changes, load studies are conducted
to determine if the system has
enough electrical capacity to handle
the proposed loads.
The three groups that may
conduct a load study include:
• Electrical contractors—who have
been hired to install new
equipment.
• The maintenance team—if they
are installing equipment.
• The utility—when a new facility
is being built and there is a
need to determine what trans-
formers and other equipment
will be needed to meet power
requirements.
In the US, regulation NEC 220.87
defines how to properly perform a
load study in order to obtain an
electrical permit.
Recognizing, identifying, and solving
power quality problems is increasingly
important to businesses—so building
this essential knowledge will help
you get to the next level. You can count
on Fluke to bring you the understanding
and the proven tools you need.

Industrial and commercial building applications
C
Energy surveys
The goal of an energy survey is to
reduce the electrical energy usage.
Simple monitoring and targeting
can discover savings opportuni-
ties by comparing daily and weekly
energy usage profiles with facilities
activities. Monitoring and targeting
can also pinpoint reductions in peak
demand charges and power factor
penalties.
An energy survey is performed over
whatever period of time captures a
representative energy profile of the
business in question. This could be
a day, week, or month depending on
industry. The facility uses the results
of the survey to guide improvements
in energy consumption, such as
installing high efficiency equipment
or correcting power factor. The test
will then be repeated to validate the
benefit of the changes.
Fluke’s new Unified
Power Measurement
(UPM) capability can also
discover energy waste
due to specific power
quality issues such as
harmonics and unbal-
ance. UPM specifically
details the energy
wasted due to the
presence of these
power quality issues.
By reducing harmonics
and unbalance you can
reduce the overall
amount of energy used.
