The VCI-3™ is a cable identification and phasing system used during installation or maintenance works on de-energized three phase systems. The VCI-3™ uses a current injection technique. The current is injected in the wire conductors or by magnetic transducers. Grounding is required at one or two ends of the three phase circuit, 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.


The tone transmitter integrates a speaker and a microphone to record the vocal identification message. The identification message is transferred by means of the current injection method directly to the cable or magnetically. Thanks to its rechargeable battery pack, it can provide more than eight hours of continuous work.


The compact detector uses a magnetic sensor. It has a built-in speaker with adjustable volume and a earphones jack to listen to the vocal identification message even in noisy environments. The sensor detection threshold is adjustable according to cable type and length. Detection is guaranteed by a digital processing system that checks for the presence or absence of every tone that comes in from the transmitter end.
