Electrical Distribution Systems

Theory: As electrical current flows through a conductor, heat is generated. Many electrical defects are accompanied by a rise in temperature for up to several weeks prior to failure. Some defects may be represented as cool components.

Improperly Closed Air Switch

Load Imbalance on Bus Duct

Loose/Deteriorated Fuse Clips

What can be detected:

  • Loose/deteriorated connections
  • Overloads
  • Imbalanced Loads
  • Open Circuits
  • Inductive Heating
  • Harmonics
  • Defective Equipment

Benefits:

  • locate problems quickly, without interrupting service
  • drastically reduce costly, unscheduled power outages
  • minimize preventive maintenance time and maximize troubleshooting effectiveness
  • prevent premature failure and extend equipment life
  • identify potentially dangerous and hazardous equipment
  • reduce insurance premiums and deductible payments

Mechanical Systems

Theory: As mechanical devices operate, heat is generated. Forces such as friction, misalignment and improper belt tension cause excessive heating.

Uneven Heating Caused by Misalignment

Defective Pillow Block Bearing

Overheated Shaft Bearing

What can be detected:

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

Benefits:

  • quickly locate misaligned coupled equipment
  • increase equipment reliability and life
  • increase production and efficiency while saving energy
  • increase quality of product
  • minimize downtime by planning the required manpower and materials before shutdown
  • improve worker productivity and morale by correcting potential problems proactively

Structural Energy Loss

Theory: Missing or damaged insulation or water infiltration into insulated systems allows excess energy loss at the point of defect. When performed under the correct conditions, thermal imaging is capable of detecting evidence of latent moisture or physical defects due to changes in either the thermal conductivity and/or thermal capacitance of the insulation system.

Q/A Inspection Detects Missing Insulation in New Building

Damaged Refractory on Boiler

Compromised Refractory in Steel Ladle

What can be detected:

  • Missing, damaged, or improperly installed insulation
  • Energy losses caused by air infiltration and exfiltration
  • Water infiltration
  • Damaged refractory

Benefits:

  • help reduce heating and cooling energy costs
  • evaluate thermal performance of retrofits
  • identify areas of latent moisture
  • detect conditions conducive to mold or insect problems
  • provide hardcopy proof of problems

Compromised Refractory in Steel Ladle

Theory: Water infiltration into low slope roofing systems causes changes in the thermal properties of the roofing system. Usually conducted at night, thermal imaging is capable of detecting evidence of latent moisture due to changes in either the thermal conductivity and/or thermal capacitance of the roofing system.

Q/A Inspection Detects Wet Insulation in New Roof

Wet Insulation Still Present After Repair

Aerial Inspection of Large Roof

What can be detected:

  • Identify latent moisture
  • Missing, damaged, or improperly installed insulation

Benefits:

  • pinpoint water-damaged roof areas quickly and accurately
  • perform quality assurance inspections of new or retrofitted systems
  • eliminate unnecessary replacement of good roof
  • identify problems early before they become large and costly
  • help extend the life of the existing roof
  • document problems before the warranty expires
  • provide facts for planning accurate budgets

Electronics Manufacture

Theory: The ability of infrared cameras to view small, irregular shaped objects and to remotely determine thermal characteristics and temperatures allow quick identification of electrical problems in their products before having to encounter more severe problems down the road.

Hot PCB (due to improper soldering of circuitry)

What can be detected:

  • Improper soldering of circuitry
  • Reversed polarity of a component
  • Erroneous component placements that cause the circuitry to heat up
  • Visualisation and quantification of heat patterns
  • Monitoring of circuit board temperatures during curing

Benefits:

  • Identify production inefficiencies
  • Improve product performance
  • Improve production processes
  • Reduced waste and increase manufacturer’s profit
  • Faster production

Surveillance and Security

Theory: Infrared cameras can be used to detect a wide range of objects without light or visibility over a short or long range.

Examples of surveillance

What can be detected:

  • Fires, even hidden grass fires
  • People & Animals
  • Vehicles and Aircraft
  • Weapons

Benefits:

  • Ability to work in smoke, fog, darkness and other conditions that would render other technologies ineffective
  • Protect physical assets and mitigate risks, day and night
  • No extra lighting required
