Equipment transferring electrical power between winding circuits.
A star winding joins one end of each phase winding at a common point.
A star winding joins one end of each phase winding at a common point. The external phase terminals and the common point determine the winding topology.
A drawn star point does not mean that it is accessible for external connection.
