Electrical power lines that carry electric energy from one point to another in an electric power system, using three power lines, to transmit three different electrical signals. The phases, or electrical signals, required for most large rotating machines which are used in many manufacturing processes and for many commercial/large wind turbines. The U.S. Department of Labor: Occupational Safety & Health Administration has a great online guide illustrating generation, transmission, and distribution equipment in an easy to understand format: http://www.osha.gov/SLTC/etools/electric_power/illustrated_glossary/inde...
