The VCI-3 is cable identification and phasing system used during installation or maintenance works on de-energized three phase systems. It uses an easy and safe voice technology to identify cables. The VCI-3 uses a current injection technology. The current is injected through the wire conductors by magnetic transducers. Grounding is required at one or two of the three-phase circuit ends, which can stay in place during the intervention to ensure maximum operator safety. The detector’s unique tone sensing system guarantees flawless and safe identification and tagging. The VCI-3 is a compact device that is very easy to use.
