NDB VCi-3™

Cable Identification & Phasing



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
