Split phase electric power
What is split phase electricity?
split phase. electricity distribution system is a 3-wire single-phase distribution system, commonly used in North America for single-family residential and light commercial (up to about 100 kVA) applications. It is the AC equivalent of the original Edison 3-wire direct current system.
What is single phase electric power?
In electrical engineering, single-phase electric power is the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors.
What are phases in electricity?
Electrical phases apply to alternating current and describe the rate at which the voltage of a given current oscillates as it is produced. "Three phase" electricity is how most domestic electricity is delivered to homes. The phases are kept 120 degrees apart so that one phase is always at a peak at any given time.
How does three phase electricity work?
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.

Split-Phase AC Induction Motor The split-phase motor is also known as an induction start/induction run motor. It has two windings: a start and a main winding. The start winding is made with smaller gauge wire and fewer turns, relative to the main winding to create more resistance, thus putting the start

Disadvantages of the split-phase design include higher cost and increased visual impact. Increased Voltage MF are proportional to current, so, for example, replacing a 69-kV line with a 138-kV line, which delivers the same power at half the current, will result in lower MF.
