Harmonic Survey Of An Mv Distribution System, Victor J. Gosbell, Damian Mannix, D A. Robinson, Sarath Perera

Faculty of Informatics - Papers (Archive)

The harmonic survey of a medium voltage distribution system involves three major aspects: (i) the choice of harmonic monitor, (ii) the choice of monitoring site, (iii) processing and presentation of results. As well as a discussion of the methodology for these aspects, the paper will discuss the harmonic levels measured, the minimum survey requirements for finding useful data and the harmonic parameters of residential, commercial and industrial loads.

Optical surface metrology techniques offer many advantages over conventional methods. Some of these advantages include a greater sensitivity and a whole field analysis that is non-contract. They also offer greater lateral and vertical resolution and are not subject to electromagnetic influence. Despite these many advantages, there has been reluctance in industry to adopt these techniques. This reluctance can be attributed to the use of high-power lasers which are considered dangerous, the expense of the systems and complicated operation and analysis procedures. The objective of the research described in this thesis was to utilise recent developments in laser diodes, data acquisition …
