Infrared Inspections
Why Perform Inspections
Infrared inspections find hot spots on electrical equipments. Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails.

In electrical systems, increased resistance can be caused by component age, fatigue oxidation, wear, loose connections or even poor installations of new equipment.

Conditions Detectable by Infrared Thermography

  • Loose and/or deteriorated connections
  • Overloaded circuits
  • Open circuits
  • Unbalanced loads
  • Inductive heating
  • Harmonics
  • Defective equipment and/or poor installations

Benefits of Infrared Thermography

  • Reduces fire/safety risks
  • Reduces unscheduled downtimes
  • Increases equipment life
  • Lowers repair costs
  • Saves money
  • Prevents catastrophic failures
  • Lowers insurance premiums due to reduced losses

Infrared Scan Uses

Drewry Electrical uses infrared scans to make sure your business or property is both safe and efficient. We offer:
  • Infrared Thermography Surveys
  • Electrical predictive maintenance
  • Mechanical predictive maintenance
We also do Electrical and Mechanical predictive maintenance as part of many Commercial and Industrial electrical services. We will go through your electrical systems and scan them for any possible red flags. We look for parts that might cause an electrical fire, break down soon from overheating and many other things. Our goal is to make sure your business is running smoothly and safely.

Infrared Thermography Services

Infra-Red scanning technology is a great tool for diagnosing and preventing electrical problems within your complex electrical systems that power your home or building. Using thermal imaging our expert technicians can quickly spot heat (or the lack of) within your wiring system and breaker panels. Areas with an unusual amounts of heat can be bottlenecks in your electrical grid that we’ll need to sort out.

Generally heat (in regards to electricity) is developed when the electricity travelling through your system encounters resistance. The resistance could be a bad breaker, a loose connection, a faulty cable or an improper hardware installation. In some cases the problem could be more serious and in those cases you’ll be both thankful and relieved that we offer this service.
