Infrared safety: using thermal technologies to protect workers
BY DOUG BARRY, FLIR Systems
Disconnect switches, elbow connectors, cutouts, lightning arrestors, oil-filled circuit breakers, and other electrical components tend to heat up before they fail. The ability to detect overheating on such equipment long before it becomes critical is essential for preventing costly unplanned outages and for protecting workers from exposure to potential arc flashes and faults. The experienced and well-trained know it’s crucial to heed...

Lineman Safety during a Wildfire
If you wanted to create a recipe for disaster, the beginning of the 2021 wildfire season would be a good place to start. Nearly 90% of the western U.S. is suffering through extreme drought. The snowpack set new low levels there as well. A record-breaking heatwave steamrolled the Pacific Northwest...
The End of the Road for Transmission Incentives
In a significant shift, the Federal Energy Regulatory Commission (FERC) has decided to abandon its transmission incentives policy, particularly the construction work in progress (CWIP) incentives. This decision marks a pivotal change in how transmission projects are financed and regulated,...
Insulation Resistance Test
Insulation Resistance (IR) test, often called Megger test, is more than 100 years old and assumed to be a very straightforward test. During my inspection and testing work in the past 15 years in Canada, US, and internationally, I have seen different practices of performing and interpretation of IR...
