Abstract

This paper presents a summary of the power quality related concerns associated with the applications of the future growth trend of neutral currents in three-phase computer power systems. These concerns include power system harmonics and neutral current caused by voltage sags and short interruption. The neutral current characteristics under that condition are described. Methods for identifying these problems, analysis, determining their impact on utility and customer are also described. The EMTP simulation, field measurement and experimental results are used to verify the disturbance problems. The applications of regression model to predict neutral current growth trend during power line disturbances from measured data is proposed
