前言:这是CSA C392《翻新期间三相鼠笼式感应电动机的测试》的第二版。它取代了2011年出版的前一版。整个标准都进行了更改。为了清晰起见，对测试程序进行了重组。要求已更新，以反映测试设备的当前能力。对测试程序的要求是强制性的。增加了一个新的非强制性附录，描述了基于空载试验确定效率估算的方法。CSA集团承认，该标准的制定在一定程度上是由BC Hydro、加拿大电力协会（CEA）和魁北克Hydro、独立电力服务运营商（IESO）、马尼托巴Hydro和加拿大自然资源部（NRCan）的财政支持实现的。 本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围:1.1本标准涵盖在50/60 Hz条件下额定功率高达15 kV的整体马力三相交流鼠笼式感应电动机。本标准还包括逆变器负载电机。注:本标准也可酌情适用于本标准范围以外的产品。1.2国际单位制给出的数值为本标准中的记录单位。括号中给出的值仅供参考和比较。 1.3在本标准中，“应”用于表示要求，即用户为遵守本标准而有义务满足的规定；“应该”用于表示建议或建议但不需要的建议；“可”用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。 附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。

Preface:This is the second edition of CSA C392,Testing of three-phase squirrel cage induction motors during refurbishment. It supersedes the previous edition published in 2011.Changes have been made throughout the standard. Test procedures have been reorganized for clarity. Requirements have been updated to reflect current capability of test equipment. Requirements for test procedures have been made mandatory. A new non-mandatory Annex has been added that describes a method to determine efficiency estimation based on no-load tests.CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, Canadian Electricity Association (CEA), and Hydro Québec, Independent Electricity Service Operator (IESO), Manitoba Hydro, and Natural Resources Canada (NRCan).This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:1.1This Standard covers integral horsepower, three-phase, alternating current, squirrel cage induction motors rated up to 15 kV at 50/60 Hz. This Standard also covers inverter duty motors.Note:This Standard may also be applied with discretion to products outside the scope of this Standard.1.2The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.1.3In this Standard, "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; and "may" is used to express an option or that which is permissible within the limits of the Standard. 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.
