Feeder Ammeter Clear Test

The FACT, Feeder Ammeter Clear Test, prevents damage to distribution feeder circuits by detecting ground connections before a feeder is energized. Distribution feeder circuits can be temporarily taken out of service for planned or unplanned maintenance. This maintenance can include replacing crossarms or insulators, reconductoring, replacing certain transformers or any other task that cannot be readily performed on a live circuit. Typical work safety practices require the installation of bolted grounds on all three phases at every location where work is being performed. ?Feed circuits are typically deenergized at a substation.

馈线电流表清除测试

FACT，馈线电流表清除测试通过在馈电线通电之前检测接地连接来防止对配电馈线电路的损坏。配电馈线电路可暂时停止服务，以进行计划内或计划外维护。这种维护可以包括更换横臂或绝缘子，重新调整，更换某些变压器或任何其他在现场电路上不能轻易完成的任务。典型的工作安全规范要求在每个正在进行工作的位置安装螺栓接地。馈电电路通常在变电站处断电。
