| IEC62689-1 | Current andvoltage sensors or detectors, to be used for fault passageindication purposes - Part 1: General principles andrequirements |
IEC 62689-1 defines the minimum requirements (thereforeperformances) and consequent classification and tests (with theexception of functional and communication ones) for fault passageindicators (FPIs) and distribution substation units (DSUs)(including their current and/or voltage sensors), which are,respectively, a device or a device/combination of devices and/orfunctions able to detect faults and provide indications about theirlocalization.
IEC 62689-1 定义了故障通道指示器 (FPI) 和配电变电站单元(DSU)（包括其电流和/或电压传感器）的Zui低要求（性能）以及后续分类和测试（功能和通信除外）)，它们分别是能够检测故障并提供关于其定位的指示的设备或设备/设备和/或功能的组合。
