True Phase Identification System SPI-III^™

Our vision has always been to create a phase identification system that exceeds any of today’s industry quality, safety and efficiency requirements. SPI-III’s unique design consists of a wireless bi-module combo that is stunningly easy to configure and operate. With many advancements and innovations, SPI-III will be more helpful than ever before, enabling field applications such as identification of A-B-C electrical phases from all 50 and 60 Hz networks, switchgear phase concordance (matching), phase rotation, system paralleling, underground phasing applications and more.

Cable identification & phasing VCi-3^™

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.

Distribution transformer tester NDB-DOC-3^™

The NDB-DOC-3™ is a test instrument designed for distribution networks transformers from 5kVA to 3MVA. It can determine the presence of short circuits or open circuits in the distribution transformer primary winding & also short circuits on the secondary winding.

The NDB-DOC-3™ is designed to be operated without disconnecting the transformer’s secondary windings from their loads.

Online partial discharge detector for overhead accessories PD-LT^™

The PD-LT™ allows for online partial discharge detection on cable accessories such as cable heads, lightning arrestors, insulators, bushings, and more. Instantaneouspartial discharge readings are transmitted to a rugged wireless display module for easy analysis.
