Benefits of IGBT Technology versus SCR Dimming
... Since IGBT dimmers are lightweight at less than 2 pounds per dimmer, more efficient at any load, create no mechanical buzz or hum, and use natural-convection cooling to produce less heat, they can be distributed adjacent to the required dimmed load. Distributed Dimming is the most cost effective way ...

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
