本加拿大国家标准适用于在交流电压超过1 kV、频率为50 Hz和/或60 Hz的电气系统上使用的电容式便携式相位比较器。本标准适用于电容式单极相位比较器，其使用的存储系统最高可达36 kV交流。，以及电容式双极相位比较器，其无线连接最高可达245 kV交流。本标准适用于电容式相位比较器，该电容式相位比较器与裸露导电部件接触，作为一个完整的设备进行比较，包括其绝缘元件，或作为一个单独的设备，适用于绝缘棒，作为一个单独的工具，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另一种设备，不在本标准范围内。例如，本标准不包括设计用作电压检测器的装置。

This National Standard of Canada 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.
