SPI-III™ True Phase Identification System

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.
