The PhaseID System now makes it possible to quickly and easily determine energized phase attributes anywhere in your system. Use it on primary, secondary, overhead, underground, livefront, deadfront, transformers, switching cabinets, substations, and standard 120-volt receptacles.
This is not a phasing stick. New innovative technology allows the phase attribute of any energized conductor to be determined by using a GPS timing signal to simultaneously measure phase at a reference location and at a field location. The readings are then compared. Since the phase attribute at the reference location is known, the phase attribute at the field location can be determined.
