Power quality issues-standards and guidelines

Abstract

As a result of the wide ranging addition of electronically controlled equipment within the last five to ten years, the lack of industry standards and application criteria in the area of power supply quality has become very evident. This paper outlines the significant factors associated with power quality by summarizing the key considerations, the relevant standards, the areas where standards are being developed, and useful application guidelines. Power quality is discussed here in terms of three major categories: system disturbances; harmonic distortion; and grounding.<>
