As part of its ongoing effort to improve the safety and reliability of its electric system, PG&E routinely uses a specialized helicopter to wash a targeted set of power lines that tend to accumulate significant amounts of contamination throughout the year such as dirt, salt and bird excrement.
Today, volt/VAr optimization is one of the key investment areas of the smart grid. It not only controls reactive power flow with drives losses on distribution feeders, but it also reduces peak demand which is critical for utilities. For more information, download Model behavior: Using distribution models to deliver smart grid volt/VAr control.
Renewables. Wind and solar are increasing their presence and importance on the grid, thanks in part to advances in technology at all levels of the power system. Download Advances in wind energy technologies in the context of smart grid to learn about some of these advancements, and how they are bringing greater control, mitigating intermittencies, and reducing the effect of electrical disturbances.
Turn data into actionable business intelligence that can increase efficiencies and support decisions across your entire enterprise. Our Advanced Distribution Management System delivers monitoring, analysis, control, optimization, planning, and training tools that all function on a common representation of your entire electric distribution network.
The Ice Buster is a high-quality tool that's designed to attach to the fiberglass hot stick you already carry on your truck, and it can be safely used from the ground without having to climb a pole or climb into a bucket. Just lift it to the wire and walk, letting it ride the line behind you. The Ice Buster turns and shears away the ice with just light to moderate effort on your part, depending on the size of the conductor and ice accumulation. In other words, it works while you walk.
SHE Transmission: Caithness Moray Transmission Reinforcement
Video describing Scottish Hydro Electric Transmission's plans to install a subsea HVDC cable between Caithness and Moray to transmit the electricity generated from renewable energy developments onto the national grid.
American Transmission Co. is proposing to reinforce the electrical transmission grid in the Upper Peninsula of Michigan and northeastern Wisconsin to address generation changes, changes in demand, the evolution of a wholesale electricity market and emerging reliability concerns.
20-minute relay retrofit: Replacing a DPU2000R with a REF615R
