The 25 kV Class 200 Ampere loadbreak separable insulated connector system didn't always have today's reputation for safety and reliability. As 25 kV Class loadbreak connectors increased in popularity in the 1980's and 1990's, utilities reported unacceptably high numbers of flashovers during energized switching operations. These line-to-ground faults were more likely to occur in colder weather, at higher altitudes, with lower load currents, and with stuck interfaces. The partial vacuum induced flashovers were not seen in 15 kV Class...
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...
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...
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...
Grounding systems are a crucially important component of any power supply system, because they directly impact public and employee safety, supply system reliability, power quality and life expectancy of power equipment. In spite of their crucial role in safe, reliable, and economic operation of...

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,...

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...
