Infrared Thermal Inspections

The National Fire Protection Agency recommends that all "critical" electrical equipment (that which seriously affects People, Property or Product) should be annually inspected using infrared thermal imaging.


Thermal inspections are an effective way to spot overloading and resistive heating in poor connections without needing to stop operations.  Detecting connection issues before a failure occurs allows for planned downtime and maintenance.  Our service people are certified level II and level III thermal / infrared thermographers in compliance with (ASNT) SNT-TC-1A (2016).

 

Breaker Showing Resistive Heating at Terminal

In power systems, a faulty connection will typically exhibit a higher than normal electrical resistance

As electrical current flows through this resistance, the conductor temperature will increase due to Joules Law or resistive heating. Infrared thermal imaging technology detects the difference in temperature and coverts it into a visible image which displays the heat signature of the object. This temperature difference is used to pinpoint the source of the fault and allows for it to be corrected before a fire or other failure occurs.

Faulty electrical Connections cause Fires, Property Damage and Lost Production

In a worst case scenario, an electrical fault causes personnel injury and property damage.

A more common scenario is that the fault damages critical equipment which must be repaired or replaced. Significant profit is lost as production is hindered or halted until the work is completed.

 

Sources of electrical faults:

 
  • Breaker Panels

  • Undersized Wiring

  • Machine Electrical Contactors

  • Disconnect Switches

 
  • Power Factor Correction Capacitors

  • Switch-gear

  • Transformers

  • Insulators and Bushings

Expert in power = expert analysis

Our experience in critical system and equipment repair gives us the distinct advantage of not only being able to identify thermal anomalies, but also to accurately assess and classify the type of anomaly as normal or serious in nature.
