Electrical systems
Thermal imaging cameras are commonly used for inspections of
electrical systems and components in all sizes and shapes.
The multitude of possible applications for thermal imaging cameras
within the range of electrical systems can be divided into two
categories: high voltage and low voltage installations.
High voltage installations
Heat is an important factor in high voltage installations. When electrical
current passes through a resistive element, it generates heat. An
increased resistance results in an increase in heat.
Over time the resistance of electrical connections will increase, due
to loosening and corrosion for instance. The corresponding rise in
temperature can cause components to fail, resulting in unplanned
outages and even injuries. In addition, the energy spent on generating
heat causes unnecessary energy losses. If left unchecked, the heat
can even rise to the point where connections melt and break down; as
a result, fires may break out.
Examples of failures in high-voltage installations that can be detected
with thermal imaging:
• Oxidation of high voltage switches
• Overheated connections •
Incorrectly secured connections
• Insulator defects
These and other issues can be spotted at an early stage with a thermal
imaging camera. A thermal imaging camera will help you to accurately
locate the problem, determine the severity of the problem, and
establish the time frame in which the equipment should be repaired.
A wide view of a substation can quickly show areas where unwanted high
resistance connections exist. No other predictive maintenance technology is
as effective for electrical inspections as thermal imaging.
One of the many advantages of thermal imaging is the ability to perform
inspections while electrical systems are under load. Since thermal imaging
is a non-contact diagnostic method, a thermographer can quickly scan a
particular piece of equipment from a safe distance, leave the hazardous
area, return to his office and analyze the data without ever putting himself
in harm’s way.
Thermal imaging cameras allow you to inspect high voltage installations
from a safe distance, increasing worker safety.
Continuity is very important to utilities since many people rely on their
services. Therefore thermal imaging inspections have become the core of
utility predictive maintenance programs throughout the world.
Thermal imaging cameras are used for inspections of electrical systems and
components in all sizes and shapes and their use is by no means limited to
large high voltage applications alone.
Electrical cabinets and motor control centers are regularly scanned with
a thermal imaging camera. If left unchecked, heat can rise to a point that
connections melt and break down; as a result, fires may break out.
Besides loose connections, electrical systems suffer from load imbalances,
corrosion, and increases in impedance to current. Thermal inspections can
quickly locate hot spots, determine the severity of the problem, and help
establish the time frame in which the equipment should be repaired.
Examples of failures in low voltage equipment that can be detected with
thermal imaging:
• High resistance connections
• Corroded connections
• Internal fuse damage
• Internal circuit breaker faults
• Poor connections and internal damage
These and other issues can be spotted at an early stage with a thermal
imaging camera. This will help to prevent costly damages and to avoid
dangerous situations.
Whether you intend to use thermal imaging cameras for
low voltage inspections in production plants, office facilities,
hospitals, hotels or domestic residences, FLIR Systems has
exactly the right thermal imaging camera for the job.

The BTU07 is a full featured and low cost BTU meter with Modbus over RS485 capability developed specifically for sub metering applications. The DFSR737A is unique among BTU meters by having the BTU calculator separate from the flow sensor, which allows the flow meter to be installed where it is needed, but with the BTU calculator and display installed anywhere it is convenient for tenant reading. The BTU07 comes as a set together with the flow and temperature sensors.

Balancing Efficiency with Comfort
WebCTRL Environmental Index – Balancing Efficiency With Comfort
As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort.
Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
