Trends in advanced motor protection and monitoring

Industrial manufacturers strive to maximize uptime of plant operations and processes. However, downtime can be a valuable asset and present many opportunities to address those critical maintenance items that can impact reliability. Since motors and associated driven equipment comprise almost 90% of the process loads, identifying and correcting these mechanical and electrical maintenance problems will reduce unplanned production shutdowns and significantly increase business profits. This paper explores the various protection technologies available to the plant and design engineer for implementation of a cost effective and reliability centered motor management program.
