Foreword

This guide addresses the specification of the (1) components, (2) protection, and (3) control of harmonic filters. It does not address the proper sizing or configuration of harmonic filters to achieve desired performance. This document provides guidelines for passive shunt harmonic filters for use on 50 Hz and 60 Hz power systems. No specific standards exist for harmonic filters, although standards do exist for virtually all of the components that are used in a filter.

Scope

This guide addresses the selection of the (1) components, (2) protection, and (3) control of harmonic filters. It does not address the engineering required to establish the proper size and configuration of harmonic filters to achieve desired performance. This document provides guidelines for passive shunt harmonic filters for use on 50 Hz and 60 Hz power systems to reduce harmonic distortion on the system(s). (No specific standards exist for harmonic filters, although standards do exist for most of the components that are used in a filter. This guide references standards where they exist and gives typical criteria where appropriate standards do not exist.)
