勘误表 1 带电作业 电压检测器 第1部分：用于电压超过 1 kV ac 的电容式检测器

[中文适用范围]： 适用于带或不带内置电源的便携式电压检测器，用于电压为 1 kV 至 420 kV ac、频率为 15 Hz 至 60 Hz 的电气系统。目前已确定： - 对于52 kV以下的电压等级，可以全部使用实际标准； - 对于52 kV以上的电压等级，电气测试程序的代表性和可行性是值得怀疑的。对于52 kV以上使用的电压探测器，制造商和客户应商定替代的电气测试安排，例如基于原国家标准的电气测试，直至本标准第二版发布。 [外文原描述]： Applies to portable voltage detectors with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 420 kV a.c. and frequencies from 15 Hz to 60 Hz. For the time being, it has been identified that : - For voltage levels up to 52 kV, the actual standard can be used in its entirety ; - For voltage levels above 52 kV, electric testing procedures are questionable from the point of view of their representativity and feasibility. For voltage detectors for use above 52 kV, manufacturers and customers should agree alternative electrical test arrangements, for example, electrical tests based on former national standards, until the publication of the second edition of this standard.
