One Infrared expert says; "With infrared, you're measuring intangibles-how much downtime you've eliminated, or how many fires you haven't had. With a utility company we can come in and say, 'If your substation goes down, you have 2,000 homes that have no meters turning for eight hours; how much does that cost?' And they can start calculating payback."

Indeed, electric utilities usually have little problem getting their moneys' worth out of infrared equipment. A senior engineering associate for Energy Transmission & Distribution Systems, New Orleans, LA, argues that he has seen a return on his company's $300,000 investment in about a year. "We have transformers that cost between four and five million dollars a piece; if we can find a problem that will save one transformer, we've paid for our program for years."

In a manufacturing plant, it often isn't quite that simple to figure Return On Investment (ROI). An expert points to equipment availability as a way of measuring payback. "If we can catch a problem before it becomes a failure and schedule the repair during a planned shutdown, we've recouped some of our investment," he says. "We have between $35,000 and $40,000 worth of equipment that we purchased about four years ago and it has paid for itself very easily."

This type of scenario is easily referenced after the purchase, but justifying costs to management beforehand can be tough. "We have documentation on steam traps," says an infrared professional, "where we look at the cost of steam production at, say, $12 to produce 1,000 lbs with a 60% efficiency in the trap. If you can reduce that figure by 25% with infrared, you can calculate very easily what the energy savings will be for that plant."

Most all newer thermal imaging cameras will be portable, handheld and will store images for documantation. The newer thermal imagers generally use the point and shoot method, and are easy  to operate. Training should be considered because while the camera does most of the work, the user needs to be able to interput the images he/she has acquired.

The more time and usage you get with the infrared camera, the more familiar you get to calling a problem.

The use of infrared thermography is likely to aid in locating potential problems, therefore reducing downtime.

Residential / commercial energy audits infrared inspections
SPi Energy Audit / Mold detection cameras An infrared home energy audit is done in two parts. First, an inspection of the exterior shows areas where expensive heated or air conditioned air is escaping. Second, an inspection of the inside shows where warm or cold air is entering. Both steps pinpoint areas where improvements can be made. Older buildings are especially vulnerable to heat and cooling loss and it is not uncommon to see entire walls, ceilings or attics lacking sufficient insulation. Thermal (Infrared) inspection is simply the best method of identifying those areas that need improvement, increasing your home's thermal efficiency and therefore saving you money! Electrical fuse and circuit breaker boxes can be checked at the same time. Checking them for hot spots. You may be amazed by some of the problems that can be found in these areas. Any time a circuit is running abnormally hot, it is costing you extra electricity. Our Infrared Imagers can also see water damaged walls, ceilings and floors. Our thermal infrared cameras see the UN-SEEN. if you have, or think you have a problem, we want to take the guess work out of fixing it, thereby saving you money on un-needed insulation, window, door or heating/central air upgrades. SPi thermal imaging & their customers is not associated with any other companies or contractors, ensuring you of an unbiased evaluation. It is our policy at to ensure the highest quality standards possible while providing the home owner with an accurate, detailed description of all areas of their residence which may be of concern.

Insulation problems can plague almost any home and even new homes can suffer. Older homes, which were not built using any type of insulation standard, should be evaluated on a consistent basis to determine if there are any problems and which of the latest technologies would most benefit the thermal efficiency of the home. Many homes which have had modern insulation upgrades or were constructed using them may be susceptible to problems which may never be diagnosed without the use of a thermal imager. Some of these include: 1. improper insulation installation. A common source of thermal efficiency problems is improper insulation installation. Often these problems are almost impossible to detect without an infrared inspection. Some of the most common problems are blown insulation which does not fill the entire cavity into which it was blown and batts of insulation which when installed were either not seated properly, were

Compressed into the cavity or do not fill the entire cavity. Batts are strips of insulation that fill the space between two studs 2. Insulation which was installed using steel staples. These staples are subject to corrosion, and it is not uncommon to see them completely rusted away. This allows the insulation to shift its position in a wall, which can result in large gaps between where the insulation has settled inside a wall and the top of the wall. These types of gaps are a substantial source of heat and cooling loss. 3. Access plates. Electrical outlets, telephone jacks, cable jacks, light switches, door bells, etc. These areas are quite often completely lacking any insulation and can be the source of annoying and normally undetectable drafts. 4. Fire Alarms, recessed lighting, ceiling fans, etc. These items installed into the ceiling, are often not insulated after installation and can be a major source of heat and cooling loss.

2. Heat and cooling loss through other areas of residence. There are tons of places in your home that your money is literally flying out the window. Some of these areas are the window and door seals of your home. The older the home, the more likely it is that there are leaks in these areas. Even new homes can suffer from problems around doors and windows. As a home settles over the course of time, the windows and door frames receive stress, this stress transforms into warping which can cause the seals to leak. You may never notice leaks like these, but they maybe there. We have seen new homes of less than 30 days old, with gaps of almost a 1/8 inch in places around the windows, these gaps were allowing air to pass in and out of the home completely unrestricted and the windows were so warped they were almost impossible to open and close. If on the coldest of days, especially when a strong wind is blowing, it seems like you just cannot keep your house warm enough, or if it seems the heating or cooling system never shuts off, than you probably have numerous small leaks. These small leaks, added up, can equal leaving a window open in your home all winter and summer. Other places of heating and cooling loss are vents, ducts and chimneys. We will look closely at all of these areas during our inspection of your home. If you have central air, or forced heat it is also possible that you are losing cooling and heating efficiency through leaks you may have in the ducts which run through your walls and attic. You could be heating or cooling these areas without ever knowing it. If there are leaks in your systems ductwork we can see them in wall cavities and the attic area.

3. Damaged areas.

SPi Infrared cameras look for areas in your home that may be damaged. Water damage is one of the most common types of damage that can lead to severe problems. It is very possible that insulation in some areas of your home have at one time or another, had water damage of some type. This type of damage does not require a visible leak into the home, and it may only occur sporadically. An example of this may be, when there is a hard rain combined with a south wind of more than 10 mph. This may only happen several times a year, however the damage that can be done over time could be substantial, plus the added water weight pulling the insulation (insulation can absorb water like a sponge) down the inside of the wall, and extra moisture corroding the staples holding the insulation up often leads to large gaps between the insulation and the upper part of a wall. Wet insulation can take months to completely dry and can be a source of mold and mildew spores, which can cause respiratory problems. Wet insulation also has an insulating property of almost zero and can actually be pulling the heat out of your home like a sponge. This type of problem is easily seen with a thermal imager. Excess moisture in an attic is a common problem in many homes and can lead to premature shingle failure. Adequate attic ventilation is essential in the resolution of this problem.

With water damage and over time, mold forms. SPi infrared cameras have the capability of “seeing” mold behind structures that could never be seen with the human eye. This makes an effective tool for mold detection. Scanning with SPI infrared cameras can determine and pinpoint mold areas which can become a potential health issue.


Large, medium and small operations have an extensive inventory of equipment requiring an uninterrupted power source for operation; an unscheduled shutdown is a disaster. Because plants and facilities runs around the clock, 365 days a year, downtime is equivalent to lost revenue.

To prevent such losses, all electrical components in the plant can be scanned with a thermal infrared imaging camera for suspect hot spots.

Some areas that can be thermally scanned are circuit breakers, transformers, fuses, disconnects switches, bus, panels, etc.

Once the problem has been detected with an Infrared imager, proper measures can then be applied for correction.

Companies use infrared imagers and thermographers to detect hot spots in electrical equipment in plants. By scanning substations, distribution lighting panels, and electrical motors. Problems are easily and quickly eliminated before they cause system failure. The results: avoidance of costly operations downtime.

By taking a thermograph of site electrical panels, thermographers develop and read a "heat picture" which reveals components that are overloaded or may become faulty. Unlike normal component operating conditions, faulty components exhibit readily detectable temperature increases over the ambient temperature profile.

Thermography verifies that electrical connections are properly made and maintained.

Thermography also detects hot spots that might be overlooked by visual inspections. Recently, in a U.S factory,    staff quickly interrupted the power supply to an above ground trailer when infrared test equipment detected a hot spot registering 123 degrees over the baseline ambient temperature. A fire could have started, resulting in the probable loss of valuable records and equipment, had the problem not been uncovered. 

Most electrical problems within industrial facilities are manifested or are accompanied by temperature changes as an effect prior to failure.  For this reason IR thermography has become an integral part of most predictive / preventative maintenance programs.  Infrared cameras can pick up small changes in temperature not visible to the human eye.  It is a non contact, non destructive, and fairly simple method of detecting impending electrical problems.

   It is widely known that as temperature in a conductor rises, so does it's resistance.   Conversely, as resistance increases (in most conductors) temperature rises.  The majority of thermal electrical problems involve improper torque specifications or improper installation at the junction points.  A loosely torqued connector effectively reduces the surface area in which current can flow and consequently an increase in the contact resistance.  Oxidation build up at the connection point can also cause a rise in resistance.  The origin of most conductor, insulation, and component problems can be traced to a poor connection using an infra-red camera.

Caution: Unless you are a qualified electrician DO NOT ever handle electrical wires, panels, or components.

   If properly conducted infrared electrical surveys are safe, fast, and reliable.  Infrared cameras are non-contact so inspections can be performed at any time without shutting down the facility.

Safety Tip: A qualified electrical contractor or facility engineer should always accompany you on the inspection.  Have them open the panels and guide your access to components.  They can also provide useful information on components you are inspecting (making your job easier).

Step 1:  Meet with appropriate staff on site and review the service order covering what will be inspected, who will accompany the thermographer, and what type of reporting is expected (i.e. videotape, written report, and / or verbal reporting). 

Step 2:  Prepare inspection with the designated staff member or electrical contractor.  Have them remove panels or prepare your access to components.   Discuss what each type of component is to determine how you will inspect it.   Have them determine (with clamp on ammeter) that electrical circuits are operating at 50% of rated load or more, if possible.

Step 3: Inspect with infrared camera.  Record the sharpest images you can.   Be wary of reflections and emissivity valuesKeep detailed records of load reading, temperature measurements, and all infrared images of any suspect components found.

Safety Tip: When inspecting electrical panels and components be aware of your distance.   High energy electrical power can arc out and ruin your day!

Step 4: Prepare the report.  Write a clear concise report of all problem areas found.  Include your load readings, live and thermal images, and properly written recommendations.

Hint: Whenever possible, inspect electrical systems when loading exceeds 50%

Problem Classification

Phase to Phase Temperature Rise



1º - 10º C

Repair in regular maintenance schedule; little probability of physical damage


10º - 30º C

Repair in the near future (2-4 weeks).  Watch load and change accordingly.  Inspect for physical damage.  There is probability of damage in the component, but not in the surrounding components.


30º - 70º C

Repair in immediate future (1-2 days).  Replace component and inspect the surrounding components for probable damage.


above 70º C

Repair immediately (overtime).  Replace component, inspect surrounding components.  Repair while IR camera is still available to inspect after.
* with wind speed less than 15mph

* with load conditions greater than 50%

Hint: Have an electrical contractor use a clamp on ammeter to verify loading.

Compensating for wind when making temperature measurements

    Wind will affect your temperature readings due to convection cooling.  This can be compensated in outdoor electrical predictive maintenance applications by multiplying your temp. reading by the correction factors listed below.

     Attention Contractors: Now is the time to invest in infrared technology.   Camera prices have reached an all time low.   An experienced thermographer can demand between $500 to $1500 per day depending on the electrical inspection performed.  A thermographer who is also an experienced electrical contractor may be able to command double that rate ( depending on experience and the nature of the inspection ).  In addition, an electrical contractor with an infrared camera can not only diagnose a wide variety of electric faults, the electrician can perform the repair generating increased revenue for the contractor and providing a level of convenience to the customer.   Contact Mike Bailey ( 805-772-0225  or mike@x20.org ) to discuss your unique situation.  Sierra Pacific Infrared can provide you with qualified thermographers to perform your customers inspections, or we can provide complete infrared camera packages including software, training, and all accessories.
