标准摘要
[中文适用范围]： IEC 61557 的这一部分规定了用于测试标称电压高达 1000V 交流和 1500V 直流的低压配电系统中的电气安全的测量和测量设备的一般要求当测量设备或测量装置涉及各种测量的测量任务时如果该系列标准涵盖了设备，则该系列标准中与每个测量任务相关的部分都适用。注：术语“测量设备”此后将用于表示“测试、测量和监控设备”。 [外文原描述]： This part of IEC 61557 specifies the general requirements for measuring and monitoring equipment for testing the electrical safety in low voltage distribution systems with nominal voltages up to 1 000 V a.c. and 1 500 V d.c. When measuring equipment or measuring installations involve measurement tasks of various measuring equipment covered by this series of standards, then the part of this series of standards relevant to each of the measurement tasks is applicable. This second edition replaces and cancels the first edition published in 1997. It constitutes a technical revision. The following changes were made with respect to the previous edition: a) revision of the definitions; b) addition of influence quantities E9 and E10; c) the subclause on Electromagnetic compatibility was complemented; d) inclusion of performance monitoring devices in the introduction; e) addition of new requirements for operating instructions.
