DEWESoft GridPhase phase identification system

DEWESoft has introduced GridPhase, a phase identification system designed to bring precision and efficiency to phase tracking across high- and low-voltage distribution networks.

GridPhase is a GPS-synchronised, handheld phase identification tool that enables field technicians, electricians and utility crews to determine which phase they are working on — even across transformer vector groups and large geographic areas. Combined with the GridPhase Reference Device and GridPhase Web platform, the system is designed to deliver an end-to-end solution for phase mapping, network maintenance and load balancing.

The handheld phase identification tool is a GPS-synchronised, Bluetooth-enabled device that pairs with a mobile app to display live phase angle, frequency, voltage readings and labels (A/B/C). A DIN rail-mountable reference device is installed at a known location (eg, a substation) to serve as the system’s phase angle baseline.

Web integration through the GridPhase Web platform allows central management of measurements, transformer compensation, and unified phase mapping across a network, while an automatic transformer phase shift compensation algorithm corrects for phase angle variations introduced by transformers, without the need for manual adjustment.

Applications include smart meter installation and commissioning, utility and DNSP network maintenance, load balancing and neutral current reduction, renewable energy connection mapping, and substation upgrades and DER integration, as well as the easy identification of phases in switchboards or fuse boxes.
