<strong>Harmonic</strong>-management solutionsfrom <strong>Schneider</strong> <strong>Electric</strong>En bref<strong>Schneider</strong> <strong>Electric</strong> offers a completerange of harmonic-managementservices:b expert analysisb measurement <strong>and</strong> surveillancedevicesb filters.9.1 Analysis <strong>and</strong> diagnosisfrom <strong>Schneider</strong> <strong>Electric</strong>Selection of the best solution, from both the technical <strong>and</strong> economic point of view,requires an in-depth study of the installation.MV <strong>and</strong> LV diagnosisWhen an expert from a <strong>Schneider</strong> <strong>Electric</strong> CEAT unit is called in, the user isguaranteed that the proposed solution will be effective (e.g. a guaranteed maximumTHDu level).The harmonic analysis <strong>and</strong> diagnosis are carried out by an engineer specialised inthe field of disturbances in electrical distribution systems <strong>and</strong> equipped with powerfulanalysis <strong>and</strong> simulation equipment.The service provided by <strong>Schneider</strong> <strong>Electric</strong> is divided into steps:b measurement of disturbances, in current <strong>and</strong> in phase-to-neutral <strong>and</strong> phase-tophasevoltages, on the disturbing loads, on the disturbed outgoing circuits <strong>and</strong> thepower sourcesb a computer model of the measured phenomena is created, providing a preciseexplanation of their causes <strong>and</strong> optimised selection of the possible solutionsb a complete report is drawn up, indicating:v the measured levels of disturbancev the maximum permissible levels of disturbance (IEC 61000, IEC 60034, etc.)b the performance of the selected solutions is guaranteedb the final solution is implemented, using the selected equipment <strong>and</strong> systems.The entire service is certified ISO 9002.To facilitate on-site expert analysis, <strong>Schneider</strong> <strong>Electric</strong>proposes a portable version of the CM4000-4000TDB105093DB105103Portable CM4000.Portable CM4000 in action.Remote monitoring of electrical installations via Internetb analyses a consumption profile to control energy costsb monitors, identifies <strong>and</strong> anticipates installation failures.DB1050914848
