"Cahiers Techniques" is a collection of documents intended for engineersand technicians, people in the industry who are looking for more in-depthinformation in order to complement that given in product catalogues.Furthermore, these "Cahiers Techniques" are often considered as helpful"tools" for training courses.They provide knowledge on new technical and technological developmentsin the electrotechnical field and electronics. They also provide betterunderstanding of various phenomena observed in electrical installations,systems and equipments.Each "Cahier Technique" provides an in-depth study of a precise subject inthe fields of electrical networks, protection devices, monitoring and controland industrial automation systems.The latest publications can be downloaded from the Schneider Electricinternet web site.Code: http://www.schneider-electric.comSection: Experts' placePlease contact your Schneider Electric representative if you want either a"Cahier Technique" or the list of available titles.The "Cahiers Techniques" collection is part of the Schneider Electric’s"Collection technique".ForewordThe author disclaims all responsibility subsequent to incorrect use ofinformation or diagrams reproduced in this document, and cannot be heldresponsible for any errors or oversights, or for the consequences of usinginformation and diagrams contained in this document.Reproduction of all or part of a "Cahier Technique" is authorised with theprior consent of the Scientific and Technical Division.

no. 152Harmonic disturbances innetworks, and their treatmentChristian COLLOMBETGraduate Engineer from INPG (Institut National Polytechnique deGrenoble), 1994. Works on short circuit current calculations inindustrial networks in collaboration with Schneider Electric, and in1995, joins the Corporate Research and Development Section wherehe undertakes research on electrical networks and their interaction onvarious equipment.Jean-Marc LUPINGraduate engineer from Ecole Nationale Supérieure d'IngénieursElectriciens de Grenoble in 1984, joins Schneider Electric in 1985, atthe technical section of Rectiphase where he takes an active part inthe design of HV capacitors, then in the development of capacitorbanks and harmonic filters. He is presently a technical expert in thatactivity, in charge of testing, standards and anticipation.Jacques SCHONEKGraduate engineer from INPT (Institut National Polytechnique deToulouse), with a Doctor's degree from the University of Toulouse,has taken part in the design of Telemecanique variable speed drivesfrom 1980 to 1995. He has then been in charge of the Harmonic Filteractivity, and is now responsible for Applications & ElectrotechnicalNetworks at the LV department.Have also taken part in the 1999 edition of this document:Noël QUILLION, author of the first edition, presently in the networks protection and controldepartment;Bruno LUSSON, harmonics specialist at "Support Services France".ECT 152 first issue, December 1999
