Infrared Thermography

Thermal imagery is an emerging science whose practical applications range from simple photography to mechanical diagnostics, and it is used extensively by firefighters and the military. In short, infrared cameras use algorithms to find differences in heat signatures from the items being photographed, regardless of the presence of ambient light.

In preventive maintenance, infrared thermography can pinpoint areas that are significantly warmer than their surroundings.  Overheating joints, faulty equipment insulation, and pending electrical shorts or faults are all invisible to the naked eye but easily detected with this method.  Advantage Reliability Services, Inc. has the equipment, the training, and the experience to utilize this technology, helping keep unpleasant surprises out of your facility.

Significant findings with Infrared Thermography include:

  • Missing or damaged insulation
  • Overloaded circuits
  • Faulty wiring
  • Loose electrical connections
  • Moisture intrusion
  • Construction defects

Example #1:

Location: Pulp Mill “C” Line Level 2 MCC

Equipment: 23-2350 #Washer Wire Turning Roll MCC AD3-A5

Problem: Ph. 1 is heating at line side of breaker.

Recommendation: Clean, lube, and tighten connections. Remove all oxides from wiring and components.

Rise: 59

Example #2:


Location: Boiler room

Equipment: CWP-1 motor.

Problem: right side (facing motor) T-lead connection is heating.

Recommendation: re-make connection, and remove all oxides from wiring and components.

Rise: 110

Example #3:

Location: Lab Hallway

Problem: Although there is no localized excessive heating at this time, this panel was previously found to be problematic and is currently fairly heavily loaded. The panel bus was found to be oxidized and will likely continue to present problems.

Recommendation: Consider replacing this panel and splitting load with another panel.
