THERMAL IMAGING INSPECTIONS

Infrared Electrical inspections are an ideal method for inspecting electrical service equipment for defective components, poor connections, and overloaded circuits. The most effective way to maintain an electrical system is to detect any potential electrical failures and take the corrective action that will prevent any interruption of the normal system operation. You can’t afford to have your plant out of operation because of an electrical system breakdown. Infrared scanning is the perfect tool for your Electrical Predictive Maintenance program. An Infrared Electrical Inspection is a cost effective means to help keep your business in operation.

Through normal use electrical equipment can become contaminated and corroded. Faulty assembly or poor installation may also lead to poor conductivity and raise the resistance level of electrical the components.

Every 12 months at a minimum, an infrared scan should be scheduled to pinpoint potential problems in primary and secondary electrical systems before a failure occurs. It is suggested that control systems and equipment subject to movement and vibration be scanned every 6 months. This economical service aids Predictive Maintenance programs that not only promotes uninterrupted system operation, but also extends the useful service life of equipment.

Electrical infrared inspections are one of the most common practices for infrared in industrial and commercial facilities. Simply put, we help reduce downtime and or catastrophic failure. 

Therma-Sonic Australia provide professional infrared electrical inspection services covering a wide variety of electrical systems for our clients.

Today’s electrical systems are complex and high performance. Excessive heat relative to the entire system can be a sign of potential problems. These higher temperatures often indicate loose or faulty connections, improper wiring, ground faults, short circuits and other common problems in the electrical equipment.

It is often difficult to determine if there is a ticking time bomb within your electrical system simply from a visual inspection. With the help of Therma-Sonic Australia and our leading-edge equipment and expertise, you can pinpoint and repair electrical problems before the equipment fails. This will ultimately reduce or eliminate your operational downtime and keep your company on a profitable path.

Mechanical infrared inspection, as with infrared electrical surveys, is another perfect match between inspection technology and the target application. All mechanical systems and individual pieces of equipment have moving parts and/or fluids. When these elements move, pivot, slide, push, pull, flow or rotate against each other or a surface, there is always some amount of friction created. There are several kinds of friction i.e. Dry friction, Fluid Friction, Lubricated friction and Skin friction, however all types of friction turn the kinetic energy of moment into thermal energy or as commonly stated, friction turns “work into heat”. It is the heat of friction, which the thermal imager can detect.

When energy is applied to make a machine do work, such as using electricity to turn a motor to rotate a pump, any excess friction will convert that electrical energy into heat. Because friction converted the input energy into heat, that energy did not go into “work” to power the pump and the energy has been wasted, dissipated as heat and thereby reducing system efficiency. Reduced system efficiency can be a factor for some companies as they work to decrease their energy usage but perhaps an issue larger than increasing efficiency may be the drag created by friction, which has the negative consequence of causing wear between the moving parts. Excessive wear leads to the premature and often catastrophic failure of moving parts which can be a danger to personnel, damage equipment and can shut down an entire production process. Product loss can occur from catastrophic failure of process equipment, which in turn can delay customer deliveries and revenue. In addition, a catastrophic failure causes the maintenance staff to react in “crises” mode to fix the failure, and unforeseen failures are usually associated with higher inventory costs to have parts on “stand by” to cover the unforeseen repairs.

Because the heat of friction is so easily seen by a thermal imager, Infrared inspections of mechanical systems is a cost-effective way to find the excessive heat of friction caused by:

  • Misalignment of coupled equipment
  • Over/under lubrication of bearings
  • Over/under tension of belted systems
  • Excessive friction
  • Defective equipment

Infrared thermal imaging inspections, when used for mechanical inspections can increase safety, prevent downtime, reduce parts inventory and prevent customer delays. All companies can benefit from having an infrared inspection of their mechanical systems as part of any preventative maintenance program.

Infrared building envelope inspection can detect air leaks (air infiltration or exfiltration), heat loss, heat gain, insulation voids, wet insulation, and can locate moisture problems in EIFS walls.

We like to think of a building envelope as a complete, monolithic covering, an impervious layer separating the inside of the building from the outside. However, some buildings thermal, pressure and vapor envelopes are not solid planes and are continually compromised!

Building envelopes are made of many differing materials and they have numerous layers of materials all peppered with penetrations such as structural expansion and control joints, electrical and plumbing conduits, in addition to numerous windows and doors and all of which need to be properly sealed in order to form a weather tight envelope around the structure. Should any of these interfaces or materials fail, or be installed/designed poorly, the structure may suffer energy loss in cold winter months and/or excessive energy gain in warmer months.

The most common heat transfer modes in buildings causing energy loss or gain are convective deficiencies such as air leaks (exfiltration or infiltration) and conductive deficiencies such as insufficient, misapplied or damaged insulation materials. In addition, these deficiencies can lead to moisture intrusion and condensation. An infrared building envelope inspection can help to evaluate the integrity of your building envelope and detect defects in the envelope.

EIFS (exterior insulation and finishing system) is typically a low maintenance design, but is subject to failures where the waterproofing surface coat interfaces with components of the building’s structure such as plumbing and electrical penetrations, windows and doors. At these locations, there can be failures such as cracks in the stucco coat due to workmanship, different expansion rates of the dissimilar materials and failures in the material or application of the weatherproofing sealants.
Wherever the thermal envelope or pressure envelope of a building is breached, infrared inspection is typically the most cost-effective, highest rate of coverage diagnostic tool available to the property owner. Using thermography to perform an infrared survey of the building can locate missing, misapplied, or damaged insulation, air leaks, and moisture intrusion areas.
