IEC 61243-1:20 21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800 kV AC、频率为50 Hz和/或60 Hz的电气系统。 本文件仅适用于与待测裸露部件接触使用的电容型电压检测器，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，本文件未涵盖（一般设计见4.4.2.1）。 本文件不涉及其他类型的电压检测器。 自测距电压检测器（正式称为“多量程电压检测器”）不在本文件范围内。 由于绝缘协调，对其使用的一些限制或正式禁止适用于IEC 62271系列设计的开关设备，在电气化铁路的架空线路系统（见附录B）和没有中性参考的系统上。对于没有中性基准的系统，绝缘水平适应于对地（地）的最大可能电压。 根据本文件设计和制造的产品有助于用户的安全，前提是这些产品由经过工作培训的人员按照热棒工作方法和使用说明使用。 除非另有说明，本文件中定义的所有电压均指三相系统的相电压值。在其他系统中，使用适用的相间或相间(地)电压来确定工作电压。 第三版取消并取代了2003年出版的第二版和修正案1:20 09。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更:a)范围更精确，指出对于这些接触电压检测器来说，只有与待测部件的裸接触才是可靠的。其基本原理是，对涂漆或涂层导体的测试导致了错误的指示，因为这种不导电的油漆或涂层根据厚度充当具有不同容量的电容器。该容量对阈值电压有影响。 b)介绍了接触探针作为一种新型的非导电接触电极。 c)定义了一种新型“专用室外型”，并将其实施到要求和测试程序中。 d)如果排除了可预见的误用，则允许使用电压和频率选择器。 e)低干扰电压的电压检测器的标记更加精确。 f）适应症组更加精确，对“准备操作状态”和“站立-按州”补充道。 g)电磁兼容性的要求和测试已经实施。 h)介绍了用于测试的良好电气连接的示例。

IEC 61243-1:2021 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, 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 document (see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B) and systems without neutral reference. For systems without neutral reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document 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 where otherwise specified, all the voltages defined in this document refer to values of phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages are used to determine the operating voltage.
This third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage.
b) A contact probe is introduced as a new type of non-conductive contact electrode.
c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure.
d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded.
e) The marking for voltage detectors with low interference voltage has been made more precise.
f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added.
g) Requirements and tests for electromagnetic compatability have been implemented.
h) An example for good electrical connection for the tests is introduced.
