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.
