What customers think about power quality

摘要

The 1990s brought about substantial improvements in the knowledge and equipment engineers use to diagnose and resolve power-quality (PQ) and reliability problems. Despite these advancements, however, it isn't easy to convince customers to implement PQ solutions. At EPRI PEAC, we've conducted more than 500 site investigations in the past six years. In the cases where we presented customers with true money-saving solutions, only half were implemented within the first year. To find out how customers perceive PQ and PQ solutions, EPRI cosponsored two information exchange forums. The first forum, hosted by Duke Energy, was held on April 18, 2000, in Charlotte, North Carolina, U.S. The Tennessee Valley Authority (TVA) hosted the second forum in Nashville, Tennessee, U.S., on Aug. 10, 2000. Both meetings brought together representatives from different industries, including the health care, textile, plastics and hospitality industries. We have broken down the feedback from each day-long discussion into three distinct areas and summarized them in the following sections.
