IEC 61481-1:2014 带电作业. 相位比较器. 第1部分: 用于超过1 kV交流电压的电容式 由 IEC 61481:2001 实时工作 - 便携式相位比较器用于电压从1 Kv到36 Kv A.c 变更而来。
This part of IEC 61481 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.@ 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. NOTE Some parts such as the contact electrode or the insulating element of a phase comparator as a complete device may be dismantled. Some restrictions on their use are applicable in the case of factory-assembled switchgear and on overhead systems of electrified railways (see Annex A). 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 (see Annex A). Products designed and manufactured according to this standard contribute to the safety of users provided they are used by persons trained for the work@ in accordance with the hot stick working method and the instructions for use. Except when otherwise specified@ all the voltages defined in this standard refer to phase-tophase voltages of three-phase systems. In other systems@ the applicable phase-to-phase or phase-to-earth (ground) voltages should be used to determine the operating voltage.
