1.1 本规范涵盖便携式、带电工具支持、直接接触式电容电压检测器，用于室内和室外电气系统，交流电压为600 V至800 kV，频率为50/60 Hz。电压检测器的功能仅限于检测是否存在标称工作电压。 1.1.1 提供了两种类型的电压检测器，分别被指定为I型、可听/可视和II型、数字型、带或不带可听。 1.1.2 提供了两种在潮湿条件下特性不同的电压检测器，分别指定为A型、室内使用和B型室内/室外使用。 1.2 这些高压探测器和任何必要的绝缘工具手柄的使用和维护不在本规范的范围内。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 注1: 除非另有规定，本规范中定义的所有电压均指三相系统中的相间电压。本规范涵盖的电压检测器可用于三相系统以外的系统，但应使用适用的相间或相对地（地）电压来确定工作电压。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本规范规定了电力行业中使用的高压探测器的设计和测试要求，以确定是否存在标称工作电压或测量电压。

1.1 This specification covers portable, live-line tool-supported, direct-contact type capacitive voltage detectors to be used on electrical systems both indoors and outdoors for ac voltages from 600 V to 800 kV with frequency of 50/60 Hz. The function of the voltage detector is limited to the detection of the presence or absence of nominal operating voltage. 1.1.1 Two types of voltage detectors are provided and are designated as Type I, audible/visual and Type II, numeric, with or without audible. 1.1.2 Two styles of voltage detectors, differing in wet conditions characteristics, are provided and are designated as Style A, indoor use and Style B indoor/outdoor use. 1.2 The use and maintenance of these high voltage detectors and any necessary insulated tool handles are beyond the scope of this specification. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1: Except where specified, all voltage defined in this specification refer to phase-to-phase voltage in a three-phase system. Voltage detectors covered by this specification may be used in other than three-phase systems, but the applicable phase-to-phase or phase-to-ground (earth) voltages shall be used to determine the operating voltage. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This specification establishes requirements for the design and testing of high voltage detectors, used in the electrical power industry, to determine the presence or absence of nominal operating voltage or the measured voltage.
