Practical approaches to reliability improvement: Line faults impact customer service, causing interruptions, sags and momentaries

摘要

Utilities are always looking to optimize their power-delivery networks to ensure customers receive appropriate levels of power quality and reliability. Although there is no magic bullet in managing power-quality issues, utilities can maximize network performance and better serve customers by diligently addressing trouble-prone areas. Significant reliability and power-quality concerns for customers include sustained interruptions, momentary interruptions and voltage sags. These problems are all caused by faults on the utility power system, with most occurring on the distribution system.
