Today, the proliferation of non-liear loads is increasing the level of harmonics disturbances and the cost of providind high-quality electrical power. At the same time, the demand for disturbance-free power is rising, driven by needs of sensitive applications involving computers, telecommunications and industrial processes.
To curb the threat posed by harmonics, the origins and dynamics of the associated phenomena must be carefully analysed and the available solutions well understood.
This publication, bringing together the experience of leading manufacturers of electrical equipement, is intended to help designers, contractors and company engineers assess the various risks and make the right decisions.
