IEC 61481-2:20 14适用于用于电压为1 kV交流电的电气系统的电阻型便携式相位比较器。至36千伏交流电。以及50Hz和/或60Hz的频率。本标准适用于电阻型相位比较器，该相位比较器与待比较的裸露导电部件接触，作为包括其绝缘元件的完整器件，或作为独立器件，适用于绝缘棒，作为独立工具，不在本标准范围内。设计用于提供相位比较以外的其他功能的设备是不同的设备，不在本标准的范围内。例如，设计为也用作电压检测器的设备不在本标准的覆盖范围内。本第一版与IEC 61481-1第一版一起取消并取代2001年出版的IEC 61481第一版，修正案1:2002和修正案2:20 04。本版本为技术修订版，包括以下主要变更: -将标准分成两部分； -审查适应症要求； -消除C类(+/-110°)； -引入新标记“LU”以供有限使用的要求； -增加网络中电压波动的指定范围以用于清晰指示； -和修订现有附件。

IEC 61481-2:2014 is applicable to portable phase comparators of resistive type to be used on electrical systems for voltages from 1 kV a.c. to 36 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to phase comparators of resistive type used in contact with the bare conductive parts to be compared as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard. A device that is designed to provide other functions than phase comparison is a different device and is not covered by this standard. For example a device designed to be also used as a voltage detector is not covered by this standard. This first edition, together with the first edition of IEC 61481-1, cancels and replaces the first edition of IEC 61481 published in 2001, Amendment 1:2002 and Amendment 2:2004. This edition constitutes a technical revision which includes the following major changes:
- split of the standard in two parts;
- review of the requirements for indication;
- elimination of class C (+/- 110°);
- introduction of a requirement for a new marking "LU" for limited use;
- increase of the specified range of voltage fluctuation in a network for clear indication;
- and revision of the existing annexes.
