At 12:15 a.m. on Sunday, May 15, 2011, an explosion and fire occurred at the Sinatra substation. As a result of the fire, numerous pieces of the bushings flew off the large 230/138-kV autotransformer and became embedded in the firewalls. Fueled by the transformers mineral oil, the fire quickly engulfed the entire transformer. Observers from nearby hotels and the interstate saw flames shoot into the dark sky, which some estimated to be as high as 80 ft (24 m). The incident made national...

This short video shows NV Energy lineman installing a new elbow with a rejuvinating fluid injection port. Once the elbow is installed on the old line, a polymer-type fluid is injected into the voids between individual conductor strands and between the conductor and the surrounding insulation. This video also shows a pressure tank slowly injecting a separate line with the fluid, which can take days to complete.

OUCTV Orlando, Florida wrote: On October 30, 2012 - 27 Orlando Utilities Commission (OUC) employees and 22 trucks traveled nearly 1,000 miles to Garrett County in Western Maryland. They have plenty of experience with heat and storms, but the mountains, cold and heavy snow from Hurricane Sandy presented a challenge.
Watch the Transpower team work overnight to remove the Pakuranga to Penrose A transmission line at the major Ti Rakau Drive / Reeves Road intersection in Pakuranga. riginally suspended from 35 transmission towers and spanning over 10 kilometres between Transpower's Pakuranga and Penrose substations, the Pakuranga to Penrose A line held its place on the skyline for over 70 years. It is being replaced with a high voltage 220 kV underground cable circuit as part of the North Auckland and...

Take a unique look at the removal of the spacers on the Pakuranga to Penrose A transmission line in East Tamaki. The 110kV transmission line is being removed as part of the North Auckland and Northland grid upgrade project and will be replaced with a higher voltage underground 220kV cable circuit.
Underground Cables - Enabler & Facilitator to achieve long term EU Energy Goals
video(36:15)|14 views
www.leonardo-energy.org The EU has established new priorities for the electricity sector, most notably security of supply is paramount and a renewable energy target of 20% by 2020. Investment in the European transmission grid has to reflect the new political decisions and this will require significant investment in the network. Achievement of priorities will require a change in mindset in transmission planning as reliance on traditional solutions based around overhead lines will not suffice...
Tree trimmers are among the 3350 line and support personnel working to restore power after a winter storm on Jan. 17, 2013, dumped heavy and wet snow in parts of Virginia, Tennessee and West Virginia served by Appalachian Power.
JEA crews headed to Baltimore and Long Island on October 28, 2012 to join other utility crews from around the country to help with power restoration in the wake of Hurricane Sandy. Utilities come to each other's aid when necessary to get power restored as quickly as possible. Learn more about JEA at www.jea.com.
Delivering industry-leading reliability takes commitment, investment, innovation and, sometimes, a helicopter full of elite, acrobatic linemen. In February 2010, FPL completed its replacement of insulators on the Martin-Poinsett 500 kV transmission line, the culmination of two years of upgrades on the power line and a crucial milestone in its 15-year plan to upgrade its 500 kV infrastructure across Florida.
