154kV WIRE STATUS INDICATOR OF 154Kv THREE-PHASE WIRE

摘要

Disclosed is a wire state indicator of a 154 kV three-phase wire. The wire state indicator of the 154 kV three-phase wire includes: a 154 kV three-phase wire (110); a current sensor (120) installed in the 154 kV three-phase wire (110); and a display unit (130) determining a live wire or a dead line in accordance with the current value of the current sensor (120) and indicating one among a live wire, dead line, or ground connection in accordance with a determination result and whether to connect the ground. The wire state indicator of the 154 kV three-phase wire determines the wire state as a live wire when the current value is a predetermined value or greater and determines the wire state as a dead line when the current value is less than the predetermined value. The wire state indicator of the 154 kV three-phase wire displays the wire state as one among a live wire, dead line, or ground connection in accordance with the determination result and whether to connect the ground. Therefore, the wire state indicator of the 154 kV three-phase wire determines the live wire or dead line in accordance with the current value of the current sensor (120) installed in the 154 kV three-phase wire (110) and displays the one among the live line, the dead line, or the ground connection in accordance with the determination result and whether to connect the ground.
