.~.~ Delta-wye, plural wye, or plural delta connected primary windings
DEFINITION
Classification: 318/771
Delta-wye, plural wye, or plural delta connected primary
windings:
(under subclass 767) Subject matter wherein the primary member comprises a plurality of windings and the circuit connected to the windings permits (a) a star-delta connection of the windings, (b) two or more star connections of the windings, (c) two or more delta connections of the windings.
(1) Note. A star connection is a polyphase circuit in which all circuit paths from each point of power connection go to a common point.
(2) Note. A delta connection is a polyphase circuit in which all circuit paths form a triangle with the apex of each path intersection being connected to a power source.
