IEC 61869-11:20 17是一项产品标准，仅涵盖低功耗无源电压互感器（无源LPVT）的附加要求。低功耗无源电压互感器的产品标准由IEC 61869-1、IEC 61869-6和具有具体要求的本文件组成。 本文件适用于新制造的额定频率为15 Hz至100 Hz的模拟输出低功率无源电压互感器，用于电气测量仪器或电气保护装置。 本文件涵盖用于测量或保护的低功率无源电压互感器和用于测量和保护的低功率无源电压互感器。 低功率无源电压互感器仅具有模拟输出（对于数字输出或使用任何种类有源电子元件的技术，请参考未来的IEC 61869-7).这种低功率无源电压互感器可以包括次级信号电缆(传输电缆)。小功率无源电压互感器的二次电压与一次电压成正比。导数输出信号不在本文档的范围内。 IEC 61869-11第一版与IEC 61869-1和IEC 61869-6一起，取消并取代了1999年发布的IEC 60044-7第一版和2002年发布的IEC 60044-8第一版的相关条款或子条款。本版构成技术修订版。

IEC 61869-11:2017 is a product standard and covers only additional requirements for low-power passive voltage transformers (passive LPVT). The product standard for low-power passive voltage transformers is composed of IEC 61869-1, along with IEC 61869-6 and this document with specific requirements.
This document is applicable to newly manufactured low-power passive voltage transformers with analogue output having rated frequencies from 15 Hz to 100 Hz for use with electrical measuring instruments or electrical protective devices.
This document covers low-power passive voltage transformers used for measurement or protection and low-power passive voltage transformers used for both measurement and protection.
Low-power passive voltage transformers have analogue output only (for digital output or for technology using any kind of active electronic components refer to future IEC 61869-7). Such low-power passive voltage transformers can include the secondary signal cable (transmitting cable). The secondary voltage of the low-power passive voltage transformer is proportional to the primary voltage. Derivative output signals are not within the scope of this document.
This first edition of IEC 61869-11, together with IEC 61869-1 and IEC 61869-6, cancels and replaces the relevant clauses or subclauses of the first edition of IEC 60044-7, published in 1999 and the first edition of IEC 60044-8, published in 2002. This edition constitutes a technical revision.
