The 160-mile, 345-kilovolt (kV) LaSalle Transmission Project, intended to connect Indiana and Illinois, is underway. It will connect three existing 345-kV substations operated by the PJM Regional Transmission Operator.
While giant steps are being taken on the national stage to upgrade the nation’s electricity transmission system and migrate to renewable power, smaller but no less important projects are underway on the local and regional level to help complete the transformation.
Case in point: Eastern Maine.
Wind power may have the potential to drastically alter our nation’s electricity consumption and reduce harmful emissions of greenhouse gases, but it will be of little use to energy consumers if the power generated can’t travel easily from the turbine to the plug.
Private and government energy experts have long agreed that major upgrades are sorely needed for our nation’s electric transmission infrastructure—-particularly for the Eastern Interconnection, a vast area composed of all the states east of the Rocky Mountains, with the exception of Texas, which is
When people in electrical construction think about outside line work, they think of overhead lines, repair work, linemen, hooks, bucket trucks and traditional distribution. They think of crews battling bad weather to restore power to places affected by ice and storms.
Dartmouth engineering professor and entrepreneur Victor Petrenko—along with his colleagues at Dartmouth and at Ice Engineering, LLC in Lebanon, N.H.—have invented a way to cheaply and effectively keep ice off power lines.
American Electric Power (AEP) is evaluating the feasibility of building a multistate, extra-high-voltage transmission project across the northern Midwest to support the development of renewable energy.
Last month, ELECTRICAL CONTRACTOR reported that the Virginia State Corporation Commission authorized construction of the Virginia segments of the Trans-Allegheny Interstate Line (TrAIL). Now, the Trans-Allegheny Interstate Line Co.
Utility planners who have been warning of a looming crisis in the U.S. electricity-transmission system for the last decade or so now may have a new weapon in their ongoing battle to expand transmission capacity.
PJM Interconnection President and CEO Terry Boston testified before the U.S. Senate Energy and Natural Resources Committee that transmission is the enabler of virtually all of the energy goals Congress is considering.
Several hazards hold the most potential for injuries No matter how comfortable an electrician feels working with electricity, danger must never be overlooked. OSHA estimates about 350 electrical-related deaths occur each year.
Article 200—Use and Identification of Grounded Conductors; Article 220—Branch-Circuit, Feeder and Service Calculations; Article 240—Overcurrent Protection; Article 310—Conductors for General Wiring; Article 314—Outlet, Device, Pull and Junction Boxes; Conduit Bodies; Fittings; and Handhole Enclosure
Interpreting swimming pool code requirements The May 2005 Code Applications column, “Going For a Swim,” contained information on a major change in Article 680 for the 2005 National Electrical Code (NEC) concerning the construction requirements of fiberglass pools, vinyl-lined pools and concrete pool
Fire pump disconnecting means Q: Is the disconnect for an electric motor driving a fire pump required to be within sight of the motor or is it permitted to be out of sight if capable of being locked in the off position? Can the disconnect and overcurrent protection be located in a panelboard?
Control-circuit transformers Q: Do the requirements of Article 450—Transformers and Transformer Vaults or Article 725—Class 1, Class 2 and Class 3 Remote-Control, Signaling, and Power-Limited Circuits apply to a control-circuit transformers in a 480-volt combination motor starter?
