Harmonics,ources of harmonics. After this, effects of harmonics in electrical machines and power system are discussed. Harmonic standards given by IEC and IEEE are referred. At the end different types of harmonic related indices are presented based on which power quality assessment may be done.

EVEN

Passivity and Activity Based Models of Polyphase System,ve been developed. After describing the main limitation of this model, activity based model has been introduced. Its equivalent circuit and layer based representation have been developed. A case study on induction machine has been done on the basis of activity based model.

André Maassen,Markus Schoenen,Ina WerrElectrical power quality is one of the most modern branches in power system study. This chapter starts with short definition of electric power quality. It describes in brief the causes of poor power quality in power system. Need of research on electric power quality is highlighted. At last, the content of the book at a glance is presented.

Die VisualWorks-Entwicklungsumgebung,This chapter presents transients as a power quality problem. It then describes the events behind the transients. Classification of power system transients is done on the basis of nature and events. Effects of transients are mentioned in short.

Offset

Die Smalltalk-Klassenhierarchie,This chapter highlights the power system disturbances related to rise or fall of rms voltage. Then it describes these disturbances one after another along with their main causes and effects.

Morose

Die Entwicklungsumgebung VisualWorks,This chapter deals with some of the power system disturbances like, DC offset, voltage fluctuation, electric noise, flicker and power frequency variation. The probable causes and effects of these disturbances are explained.

flourish

Ein Server, der HTTP-Kommandos analysiert,This chapter starts with an introduction of unbalance assessment. It then describes sequence components in three phase system. Unbalance is assessed using sequence components. A case study has been shown on single phasing of an induction machine. Generation of sequence components along with their phase shift has been mathematically explained.
