In Canada, lightning flashes occur about 2.34 million times a year; with the highest levels of concentration during the summer months.
While most lightning on earth is ground-to-cloud, recent research has identified that the majority of lightning events to tall structures, such as wind turbines, occur in the presents of ground-to-cloud leaders – upward lightning. More importantly, the majority of ground-to-cloud leaders transpire following a sudden change in electric field initiated by either cloud-to-cloud, cloud-to-air...
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...
Protecting utility workers with documented reporting BY MIKE DOHERTY, PowerTel Utilities Contractors Limited Within the lineman trade, accountabilities for the documentation of various inspections, job safety analyses (JSAs), audits, safe work practices (SPGs), qualifications, safety meetings,...
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...
How Ontario regulation can improve electrical safety BY BILL KHASHFE, London Hydro According to an Ontario Electrical Safety Report, 35 percent of the province’s electrical-related fatalities in the past 10 years were attributed to power-line contact. Equipment specifications and electric utility...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
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,...
Verifying the functionality and integrity of a grounding system is critical to maintaining a safe workspace. Unfortunately, the tests used to achieve this goal, as well as the standards used to assess them, have required a specialized skillset, often leaving these tests done improperly or not at...
For years, manufacturers of ground rods have strived to develop technical specifications for the electrical industry which address the specific needs and applications of clients and endusers alike. One reason for stressing the importance of this was to assure that the customer would receive what...
Taking care of your grounds and jumpers A lineman’s ground and jumper cables look and feel like they’re built to last forever, but looks can be deceiving. They get tossed in the truck, dropped in the mud, left hanging in the rain, and generally overlooked. With everyday use, we start...
When working in close proximity to exposed energized equipment or working on live electrical circuits, it’s necessary to protect not only the equipment being worked on but also the worker. Rubber insulating gloves and insulated hand tools are vital components of a successful PPE system and...
