    Product Details

    • Preface/Scope
    Preface

    This is the first edition of CAN/CSA-C22.2 No. 257, Interconnecting inverter-based micro-distributed resources to distribution systems. It is one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It is written in SI (metric) units.

    Scope

    1.1
    This Standard specifies the electrical requirements for safe interconnection of inverter-based micro-distributed resource (micro-DR) systems to low-voltage systems connected to distribution systems. The output of these systems is limited to 600 V (nominal) or less (single or three phase).

    1.2
    Intentional islanding conditions and interconnection to secondary networks are not covered in this Standard.

    Note: Inverter types and operating modes are provided in Annex F.

    1.3
    In CSA Standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability.

    Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

    Notes to tables and figures are considered part of the table or figure and may be written as requirements.

    Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
