A cement plant's experience in investigating power sags leads to a reduction in kiln outages by utilizing power hardening methods

摘要

Poor power quality can be a cause of several process interruptions, including kiln outages at a cement plant. The purpose of this report is to educate the reader on voltage sags, which are the most common power quality issue faced by an industrial plant. Industrial end-users should understand why they should be concerned about voltage sags at their facility and how the severity of a voltage sag can be quantified then related to the sensitivity of the installed plant equipment. This in turn can result in applying power hardening methods to process equipment that will benefit the facility by reducing the number of power quality related process outages.
