本指南包含进行普遍适用和公认的测试以确定同步电机性能特征的说明。尽管所述试验通常适用于同步发电机、同步电机（大于分数马力）、同步冷凝器和同步变频器，但本说明主要参考同步发电机和同步电机。根据需要，所述试验可适用于电机和发电机，且不试图将本指南划分为适用于电机的条款和适用于发电机的条款。 本指南不应涵盖所有可能的测试或研究性质的测试，而应仅涵盖可用于获取性能数据的一般方法。新设备可能需要的工厂和现场试验时间表通常由适用标准或合同规范规定。本指南不应被解释为要求在给定交易中进行任何特定测试，或暗示对特定性能指标或操作条件做出任何保证。 除非另有约定，否则本指南中使用的术语规定的试验条件将被视为额定条件。额定条件通常适用于机器铭牌上列出的数量。

This guide contains instructions for conducting generally applicable and accepted tests to determine the performance characteristics of synchronous machines. Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than fractional horsepower), synchronous condensers, and synchronous frequency changers, the descriptions make reference primarily to synchronous generators and synchronous motors. The tests described may be applied to motors and generators, as needed, and no attempt is made to partition this guide into clauses applying to motors and clauses applying to generators. It is not intended that this guide shall cover all possible tests or tests of a research nature, but only general methods that may be used to obtain performance data. The schedule of factory and field tests, which may be required on new equipment, is normally specified by applicable standards or by contract specifications. This guide should not be interpreted as requiring any specific test in a given transaction or implying any guarantee about specific performance indices or operating conditions. The term specified conditions for tests as used in this guide will be considered as rated conditions unless otherwise agreed upon. Rated conditions apply usually to the quantities listed on the machine nameplate.
