Commissioning of Induction Motors Larger than 250hp What is Motor Commissioning and Why is it Important?

Abstract

It is commonly believed that if a motor surpasses the infant failure state trouble free, it will probably provide several years of reliable service. Traditional installation services unfortunately frequently do not identify and correct common causes of such infant failures, resulting in costly unplanned downtime shortly after a plant start-up. This paper proposes an approach to motor commissioning that aims to identify infant failure even before the plant is returned to service, thereby avoiding these costly productions losses, and providing opportunity for real time plant improvements and optimization.
