BriteSpot™ Thermal Monitoring
INSTANT. ACCURATE. 24/7 FIBER-OPTIC TEMPERATURE MEASUREMENT
INTRODUCING BRITESPOT™
Due to the heat generation of electrical currents,
temperature monitoring has become an efficient way
to predict potential equipment failure. Overheating
may be caused by loose or deteriorated connections,
overloaded circuits or imbalanced loads. Thousands
of dollars in downtime and repair expenses have been
saved each year through the detection of electrical hot
spots.
Powell is proud to introduce the BriteSpot™ fiber-optic
temperature sensor as the best solution for accurate and
consistent recording of electrical temperatures at areas
of concern. When mounted on bus bars, splices, circuit
breaker disconnects or cable connections, you will
know immediately if thermal issues are arising. This field
proven fiber-optic technology logs temperature data
24/7/365.
Real-Time Thermal Monitoring
Electrically Non-Conductive Optical Fiber
Install in any Manufacturer’s Equipment
Secure and Solid Connection Point
MODBUS RS-485 Interface
The basic principal behind the operation of BriteSpot
is the use of light transmitted over polymer fibers.
The properties of the light are modified as the
temperature of the sensing tip changes, allowing for
accurate determination of temperature. By using light,
the fibers do not require any electrically conductive
elements, allowing them to be used safely in electrical
environments. The fiber cabling can be routed around
live components without degrading the dielectric
integrity of equipment. As an added benefit of the
technology, there is no calibration needed for the
lifetime of the product.
Superior to Periodic Testing
ADVANTAGES OVER INFRARED (IR)
Monitor Inaccessible Locations
Fiber-optic technology has several key advantages over
periodic IR scanning. The most obvious benefit comes
from the real-time nature of the data and the ability to
monitor locations inaccessible to IR scanning; in circuit
breaker compartments, behind barriers or inside bus
duct.
Powered by Safety®
“Continuous thermal monitoring not only
allows our facility to eliminate thermal issues
as a part of our risk assessment analysis, but
provides data in locations not accessible while
equipment is energized, for example, in main
bus compartments.”

ANALYZING THE DATA
LOCAL LED DISPLAY
The BriteSpot™ front faceplate has an LED window
to display the monitored temperatures as well as
selectable buttons to customize features for the
user. These features include toggling the desired
measurement between Celsius and Fahrenheit, setting
the rate of logging at either 15/30/60/120 minutes,
identifying the alarm trip set points (LED display will
blink when reached), and defining other communication
parameters.
DATA MONITORING
The BriteSpot™ conversion module is typically
mounted inside the low voltage control section of
any manufacturer’s equipment. It has 4MB of memory
storage with a real-time clock for data time stamping.
The logged data can be exported either by an RS-485
MODBUS® link to an existing SCADA network or simply
exported locally from the BriteSpot™ faceplate utilizing a
standard USB cable.
Once temperature data is aggregated, how do you know
if a true problem exists? The answer lies in a combination
of the users experience with the equipment and its
ratings, temperature data, environmental data, power
data, and possibly other historical data. Once combined,
the data can be trended and inconsistencies identified
thus aiding personnel to predict asset reliability and life
cycle status.
INSTALLATION OPTIONS
BriteSpot™ installation requires no specialized tools
or training. Standard tinned-plated copper ring lugs
are provided in1/2”, 3/8” and 1/4” sizes for installation
variances. The fiber probe is attached to the lug and is
secured to the point of concern. BriteSpot logs absolute
temperatures and removes temperature variances found
in other measurement methods.
