Power Quality and Utilisation Guide

The Power Quality and Utilisation Guide is a unique reference source providing not only background theory, but also a whole range of solutions from industry. Prepared by specialist authors from industry and academia, and edited by Copper Development Association's David Chapman, the Guide is organised into 8 sections and presented in a series of short Application Notes.

Application Notes are downloadable individually in pdf format or as a fully searchable library.
