Three lines meeting at a common point.
Also known as: Wye connection symbol, Y connection, Neutral point connection
A star or wye connection joins one end of each of three windings at a common point, giving access to a neutral. It is drawn as three lines meeting at a centre, and choosing it over a delta connection changes the voltage each winding sees by a factor of the square root of three.
Denotes a three-phase connection in which one end of each winding is joined at a common point, making a neutral available.

Presents each winding with the line voltage divided by the square root of three, which is the reason a motor can be started in star and run in delta.
Contexts: Technical drawing, Electrical equipment
Three straight lines of equal length radiating from a single central point at equal angles.
