Switchgear | ABB help plant operators understand how digital switchgear can help overcome the hidden costs of traditional switchgear by improving your ability to collect, access, analyze and take action on the data your equipment and infrastructure creates, helping you achieve cost savings of up to 30 percent.
Introduction to Traction Substations on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations are used to convert electrical power as supplied by the power utility (or rail operators own network) to a form suitable for providing power to a rail system (via third rail or overhead line).

Power engineers what is the future of the industry ... carbon emissions, most coal plants in operation today are either relatively clean or else putting in the infrastructure to control their emissions. Unless the government loosens up on nuclear regulations, I think coal/gas will be a big part of generation until the issues with renewables are worked out (storage, price, infrastructure).
