NDB VCI-3D-CLAMP-BC Detector Clamp

Clamp on type sensor with built-in passive filter, used with detector module.

Application: Unipolar cable identification with great immunity to external magnetic fields.



The VCi-3™ system is designed for cable and phase identification, mainly for instal­lation or maintenance purposes on three-phase electrical networks during power shutdowns.

The transmitter module injects a low current on the cable conductors by direct con­tact or magnetic clamps methods. A voice message is recorded by the user and will be transmitted along with digital signals. Groundings stay connected at both ends of the three-phase circuit during the test. The detector module is used at the other end of the cable system.


• Unique balanced injection system that eliminates signal bleeding on other wires
• Three different frequencies to identify each phase
• Easy to install and operate
• Extended range: up to 10 km (6 miles) of working distance
• Tone transmission for more than 8 hours
• Lightweight and compact
• Optional magnetic sensing transducer
• Phase detection by transmitter tone presence or absence
• Digital filtering of network harmonics
• Unique dual grounded method
