Electrical installations of buildings-Part 5-Selection and erection of electrical equipment-Section 551: Low-voltage generating sets

Document Number: NL IEC 60364 5 551 : 2003
Sector: Electrical Engineering
TC: NL TC EO
ICS: 91.140.50
This section of IEC 60364-5 applies to low-voltage and extra-low installations which incorporate generating sets intended to supply, either continuously or occasionally, all or part of the installation. Requirements are included for installation with the following supply arrangements: Supply to an installation which is not connected to the public supply Supply to an installation as an alternative to the public supply Appropriate combinations of the above. This section does not apply to self-contained items of extra-low voltage electrical equipment which incorporate both the source of energy and the energy-using load and for which a specific product standard exists that include the requirements for electrical safety. NOTE Particular requirements for supplies for safety services are given in IEC 60364-5-56 Requirements of the public supply undertaking should be ascertained before a generating set is installed in an installation which is connected to the public supply Generating sets with the following power sources are considered Combination engines Turbines Electric motors Photovoltaic cells Electrochemical accumulators Other suitable sources Generating sets with the following electrical characteristics are considered: main-excited and separately excited synchronous generators; mains-excited and self-excited asynchronous generators; main-commutated static inverters with or without by-pass facilities L’utilisation des groups generateurs pour les usages suivants est prise en consideration Alimentation d’installation permanents Alimentation d’installations temporaires Alimentation de materiels mobiles non relies a une installation fixe permanente
