IEC 61243-3:20 14适用于手持式两极电压检测器及其附件（鳄鱼夹和可拆卸导线），用于与交流电气系统部件接触。标称频率在16 2/3 Hz至500 Hz之间时，电压不超过1 000 V，和/或直流。电压不超过1 500 V。本标准不包括接触电极延伸部分。本标准涵盖的电压检测器旨在室内和室外的干燥和潮湿条件下使用。它们不打算在下雨的情况下使用。本标准涵盖的电压检测器不打算用于连续操作。本标准涵盖的电压探测器旨在用于海拔2 000 m以上的地方。本标准还包括以下补充功能（如有）的规定:-相位指示； -旋转场指示； -和连续性检查。其他补充功能不在本标准范围内。本标准涵盖的电压检测器不被视为测量设备。测量装置的相关安全要求包含在IEC 61010系列中。 这第三版取消并取代了2009年出版的第二版。这是一次技术修订，与上一版相比，包括以下重大技术变更: -管理电源频率干扰电压的要求和测试； -以及关于电压检测器和干扰电压存在的信息附件。

IEC 61243-3:2014 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or for d.c. voltages not exceeding 1 500 V. Contact electrode extensions are not covered by this standard. Voltage detectors covered by this standard are intended to be used under dry and humid conditions, both indoor and outdoor. They are not intended to be used under rain conditions. Voltage detectors covered by this standard are not intended to be used for continuous operation. Voltage detectors covered by this standard are intended to be used up to 2 000 m above sea level. This standard also includes provisions for the following supplementary functions when available:
- phase indication;
- rotating field indication;
- and continuity check. Other supplementary functions are not covered by this standard. Voltage detectors covered by this standard are not considered as measuring devices. Relevant safety requirements for measuring devices are included in IEC 61010 series. This third edition cancels and replaces the second edition published in 2009. It is a technical revision which includes the following significant technical changes with respect to the previous edition:
- requirement and test to manage interference voltages at power frequencies;
- and informative annex on voltage detectors and the presence of interference voltages.
