5 Easy Ways to Reduce Energy Waste with Ultrasound

Did you know that an energy efficient facility can be directly linked to its reliability and success? Are you aware of how important it is to consistently report and document results to generate awareness and effectively reduce your energy usage? What about how important it is to be proactive instead of reactive to prevent problems from happening in the first place? Common sense will have you answer these questions with, “Yes,” but the way you run your facility could be suggesting…

Inductive Heating Hotspots

Loose connections, overloading and imbalanced loads cause overheating of components within an electrical system. Depending upon construction and operation of the electrical system, a perplexing and possibly serious condition called inductive heating can cause non-current carrying components to overheat.

Using Acoustic Imaging for Partial Discharge Monitoring

Partial discharge (PD) is a maintenance challenge found on high-voltage equipment around the world – especially older, aging infrastructure. Predictive maintenance workers are now starting to use acoustic imaging to target PD by finding its distinctive sound signature even before equipment overheats. Source: IR/INFO.ORG…

Detecting Delamination of Stucco

With aging infrastructure becoming an increasing concern in many communities, more attention is being focused on the maintenance of building facades. Under the right conditions, thermal imaging can detect evidence of delaminated stucco or concrete finishes on the exterior of masonry buildings. Source: IR/INFO.ORG…

Significant Changes in the 2021 Edition of the NFPA 70E Standard for Electrical Safety in the Workplace

IR Inspections of Parking Garage Ceilings

When inspecting building envelopes for heat loss, thermographers tend to focus their imaging efforts on the sidewalls and roof. For some buildings, it is important to also thermographically inspect the underside of the building. Source: IR/INFO.ORG…

How Delta T’s Understate Priorities

For years, thermographers have traditionally reported apparent Delta T measurements when documenting their findings. Using a default emittance value between .8 and 1.0, apparent temperature measurements are recorded regardless of actual target emittance. While this methodology is fast and easy, it can lead to significantly understated Delta T repair priorities. Source: IR/INFO.ORG…
