Infrared Thermal Inspections

Spot Issues. Fix Problems. Reduce Downtime.

Example: Overheating 13kV bus connection

Thermal inspections are an effective way to spot overloading and resistive heating in poor connections without stopping operations.  Detecting connection issues before a failure occurs allows for planned downtime and maintenance. 

Our qualifications:

  • Certified in Compliance with ASNT SNT-TC-1A (2020)

  • Specializing in Industrial Power Distribution Systems

  • ANSI / NETA Compliant

  • OSHA 1910 and NFPA 70 Arc Flash Compliant

Example: Transformer, tilted with low oil

Inspectors are certified Level II thermal/infrared thermographers compliant with ASNT SNT-TC-1A (2020).

  • Over 70 hours of training

  • Minimum 1,800 hours of experience

  • Certified in arc flash and electrical shock safety

  • Full compliance with ANSI / NETA MTS-2019 (maintenance testing specifications)

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

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 temperature difference and converts it into a visible image that displays the object's heat signature. 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.

 

Sources of electrical faults

Example: Damaged lighting contactor

Faulty electrical connections cause fires, property damage, and lost production.

An electrical fault causes personnel injury and property damage in a worst-case scenario.

A typical 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.

 
 

  • Breaker Panels

  • Undersized Wiring

  • Machine Electrical Contactors

  • Disconnect Switches

 

  • Power Factor Correction Capacitors

  • Switch-gear

  • Transformers

  • Insulators and Bushings

 
 

Example: ‘B’ phase fuse with high resistance connection

Expert in power = expert analysis.

Avoid false alarms and incorrect diagnoses.

If a problem is found, we accurately identify, assess, and classify it.
