EN 50438:2007

Requirements for the connection of micro-generators in parallel with public low-voltage distribution networks

This European Standard specifies technical requirements for connection and operation of fixed installed micro-generators and their protection devices, irrespective of the micro-generators primary source of energy, in parallel with public low-voltage distribution networks, where micro-generation refers to equipment rated up to and including 16 A per phase, single or multi phase 230/400 V or multi phase 230 V (phase-to-phase voltage). This European Standard is intended for installation mainly in the domestic market.

Anforderungen für den Anschluss von Klein-Generatoren an das öffentliche Niederspannungsnetz

Diese Norm spezifiziert die technischen Anforderungen für den Anschluss und den Betrieb von fest installierten und parallel mit öffentlichen Niederspannungs-Verteilungsnetzen betriebenen Kleinerzeugern und ihrer Schutzeinrichtungen, unabhängig von der verwendeten Primärenergiequelle. Kleinerzeugung umfasst Geräte mit Bemessungsströmen bis maximal 16 A pro Phase und Bemessungsspannungen ein- oder mehrphasig 230/400 V oder mehrphasig 230 V (Außenleiterspannung). Die Norm bezieht sich insbesondere auf Installationen im Hausbereich.

Prescriptions pour le raccordement de micro-générateurs en parallèle avec les réseaux publics de distribution à basse tension

Cette Norme Européenne spécifie les exigences techniques pour le raccordement et le fonctionnement des micro-générateurs installés à poste fixe et leurs dispositifs de protection, indépendamment de la source d’énergie primaire des micro-générateurs, en parallèle avec les réseaux publics de distribution à basse tension, où micro-génération fait référence à des équipements dimensionnés jusqu’à et incluant 16 A par phase, monophasés ou polyphasés 230/400 V ou polyphasés 230 V (tension entre phases). Cette Norme Européenne est destinée aux installations principalement du marché domestique.
