Voltage and current waveforms provide the most precise insights into power system behaviours. Time synchronisation enable large-scale, coordinated analysis of waveforms across vast areas. Such advancements enables new concepts, strategies, and tools for monitoring, protecting, and controlling power systems and equipment. GPS based time synchronisation of waveform data from multiple locations was introduced by CT LAB in the VECTOGRAPH Power Quality meter in 1995. The latest, fourth generation VECTO 3 provides just such a comprehensive toolkit to power system managers.
VECTO devices can operate stand-alone or as part of a fleet of permanently connected devices managed by VECTO Grid OS, the big data hosting, visualisation, analysis & reporting software platform.
