A Filtering Technique for Three-Phase Power Systems
2005 IEEE Instrumentationand Measurement Technology Conference Proceedings, 2006A novel filter for use in three-phase power systems is introduced. When the input to the filter is a balanced three-phase set of signals, the filter suppresses noise and distortions and extracts a smooth three-phase fundamental component. When the input signal to the filter is unbalanced, it extracts the fundamental positive-sequence component of the ...

Three-Phase Power System and Three-Phase Transformers
2011Single-phase systems are adequate for residential applications up to an apparent power S of 5 kVA (per residence), and 25 kVA single-phase pole transformers supply power to about 5–10 residences. In rural areas irrigation applications require single-phase motor ratings of up to 50 kVA.

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.

SAN FRANCISCO saw the opening of the first central power station in 1879, supplying DC from two Brush dynamos to arc lamps for lighting the streets. Similar systems were soon installed all over the world. AC generators began to be used for the same purpose and the two varieties of electricity supply coexisted for a time, with the advantage perhaps ...

Power quality analyzer for three phase systems
2013 International Conference on Renewable Energy Research and Applications (ICRERA), 2013In this study, a MATLAB based simulator is designed which can be used for education in power quality and harmonics. The designed simulator is user-interactive and also can be used in undergraduate and graduate laboratory studies. The harmonic components that are entered by the user are visualized graphically.
