EN IEC 62962:2019

Particular requirements for load-shedding equipment (LSE)

IEC 62962:2019 The purpose of this document is to provide requirements for equipment to be used in energy efficiency systems. This document covers load-shedding equipment (LSE). Guidelines relating to safety for LSE as given in IEC Guide 110 have been followed. This document applies to load-shedding equipment for household and similar uses. The load-shedding function is used in energy management systems to optimize the overall use of electrical energy including production and storage. Load-shedding can be used for example for energy efficiency purposes as per IEC 60364-8-1:2019.

Exigences spécifiques pour les délesteurs (LSE)

IEC 62962:2019 L'objet du présent document est de fournir les exigences pour les équipements à utiliser dans les systèmes d'efficacité énergétique. Le présent document couvre les délesteurs (LSE). Les lignes directrices concernant la sécurité des LSE, telles qu'elles sont énoncées dans le Guide IEC 110, ont été respectées. Le présent document s'applique aux délesteurs destinés à un usage domestique et à des usages similaires. La fonction de délestage est utilisée dans les systèmes de gestion d'énergie pour optimiser l'usage global de l'énergie électrique, comprenant les applications de production et de stockage. Le délestage peut par exemple être utilisé à des fins d'efficacité énergétique, conformément à l'IEC 60364-8-1:2019.
