A study of some three-phase systems
Proceedings of the American Institute of Electrical Engineers, 1914The star-star, delta-delta, delta-star and star-delta connections are taken up in order and their individual peculiarities and characteristics, precautions that must be taken in operation to avoid trouble, and where and when the system may be grounded with best results, are discussed. The question of delta-delta vs.

A study of a queueing system with three-phase service
Operations Research Letters, 1993The paper considers a single server which alternates between a batch service queue and an individual service queue. The service times are generally distributed with the batch service queue having two phases of service, the first following a non-gated protocol and the second a gated protocol.

A three-phase supply system is produced by three sets of windings on an alternator, the windings being displaced from one another around the alternator rotor by 120°. Three-phase systems have a number of advantages over single-phase systems including the fact that, for a given amount of power transmitted, the total power loss is less than in three ...

Three-Phase Electrical Systems
2020Most of the AC machines are constructed with three-phase windings in the stator. The compression and analysis of AC machines can be complicated in three-phase systems, especially when there is a moving part, such as the rotor, which, depending on its position relative to the stator, the results of the equations can take different values.
