Abstract
This paper provides a general overview of harmonics and addresses the causes of current generated harmonics in electrical systems. In addition, problems caused by current generated harmonics and their affects upon different types of electrical equipment; such as cables, meters, capacitors, motors, transformers, emergency generators, etc. are presented. Recommendations for solving harmonic problems are also provided. The paper discusses and analyzes two actual cases where harmonics caused problems in electrical systems, one case a computer center and the other an oil collection system using variable frequency drives (VFDs) for oil well pumps. The paper also discusses where the public utility industry appears to be headed in addressing harmonics.
