Fault-location equipment supports the investigation of an insulation fault by indicating the circuit or branch associated with the event. The number of monitored branches and the locating method must be confirmed from the product data and project design.故障定位设备用于帮助查找出现绝缘异常的出线回路。可监测的支路数量和定位方式需依据具体型号资料及项目设计确认。

Fault-location systems故障定位系统
A clearer route from an insulation alarm to the affected outgoing circuit, subject to the chosen monitoring and locating architecture.绝缘报警出现后，帮助维护人员排查相关出线回路。具体定位方式和能力取决于设备配置与系统设计。
Planned alongside the insulation monitoring device and the outgoing circuit layout. Branch identification should match the panel schedules and room documentation used by the project team.应结合绝缘监视仪和配电盘出线布局进行配置。支路编号需与配电盘回路表及房间资料保持一致。

04 / BEFORE YOU SELECT选型前确认
Questions to resolve before selecting a model.确定型号前，先确认这些问题。
- 01
How many outgoing circuits need to be distinguished?需要区分多少条出线回路？
- 02
Do branch names match across drawings, panels and alarm displays?图纸、配电盘和报警显示中的支路编号是否一致？
- 03
Which locating components and wiring method does the selected system require?所选系统需要哪些定位组件？接线方式是什么？
