IEC 61481-1:20 14适用于电压超过1 kV交流电的电气系统上使用的电容型便携式相位比较器。以及50Hz和/或60Hz的频率。本标准适用于交流电最高36 kV的存储器系统工作的电容型单极相位比较器，以及交流电最高245 kV的无线连接工作的电容型两极相位比较器。本标准适用于电容型相位比较器，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 61481-2第一版一起取消并取代了2001年出版的IEC 61481第一版、修正案1:20 02和修正案2:20 04。此版本是一个技术修订版，包括以下主要变化: -将标准分成两部分； -扩展范围以包括以高达245kV交流电的无线连接操作的两极相位比较器； -审查适应症要求； -引入新标记“LU”以供有限使用的要求； -以及修订现有附件。

IEC 61481-1:2014 is applicable to portable phase comparators of capacitive type to be used on electrical systems for voltages exceeding 1 kV a.c. and frequencies of 50 Hz and/or 60 Hz. This standard is applicable to single-pole phase comparators of capacitive type operating with a memory system up to 36 kV a.c., and two-pole phase comparators of capacitive type operating with a wireless connection up to 245 kV a.c. This standard is applicable to phase comparators of capacitive 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 61481-2, 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 including the following major changes:
- split of the standard in two parts;
- extension of the scope to include two-pole phase comparators operating with a wireless connection up to 245 kV a.c.;
- review of the requirements for indication;
- introduction of a requirement for a new marking "LU" for limited use;
- and revision of existing annexes.
