Most process plants employ automatic switching schemes to maintain operation through power system disturbances. An understanding of motor behavior through such disturbances is helpful in the application of selective fault clearing, fast bus transfer, and delayed bus transfer schemes. Results and conclusions of computer aided transient studies of major(More)
One of the major factors to be considered in selecting the ratings of electrical equipment (circuit breakers, bus bar bracing, etc.) is the level of three-phase short circuit current available at the equipment location in the system. The total three-phase short circuit current at a faulted point includes both the currents from the power source (such as(More)
In a downhill conveyor system, the drive motors become generators feeding real power to the electrical system. A general method using the cascade network concept and a digital computer is proposed to study the conveyor motors' operation in the motoring and generating modes. By use of the proposed method, a long downhill conveyor system with many stages of(More)
The purpose of our study was to establish the guidelines for interpreting neonatal flash visual-evoked potentials (FVEPs) by examining the correlation between maturation of the waveforms and conceptual age (CA). We retrospectively analyzed 220 consecutive neonatal FVEPs performed on premature and full-term infants. The CA of the participants ranged from 28(More)
Reliability and availability (R&A) studies have been made a part of the IEEE Recommended Practice For Industrial and Commercial Power System Analysis (IEEE Standard 399-1980). R&A studies should improve the selection of system configurations and components by basing decisions on quantitative information rather than on intuitive and qualitative decisions.(More)
