An algorithm for optimal sizing of the capacitor banks under non-sinusoidal and unbalanced conditions [PDF]
, 2014 In non-sinusoidal and unbalanced systems, optimal sizing of the capacitor banks is not a straightforward task as in sinusoidal and balanced systems. In this paper, by means of qualitative and quantitative analysis, it is interpreted that the classical ...

Power factor and unbalance on a polyphase system [PDF]
Journal of the American Institute of Electrical Engineers, 1920 In a single-phase or balanced polyphase circuit, the two factors which are contributory to power factors less than unity are wave distortion and phase displacement between current and voltage. In the paper the influence of wave shape is not considered, since in most large modern systems the wave form is nearly sinusoidal.

Design and application of squeeze film dampers for turbomachinery stabilization [PDF]
, 1975 The steady-state transient response of the squeeze film damper bearing was investigated. Both the steady-state and transient equations for the hydrodynamic bearing forces are derived; the steady-state equations were used to determine the damper ...
