When an outage occurs, repair of distribution infrastructure can sometimes lead to meters being reconnected to the wrong transformer or phase, which leads to issues with grid balancing. [Frost and Sullivan recognises Itron as ‘Smart Grid Solutions Company of the Year’]
“Traditionally, verifying transformer and phase connectivity has required either visual tracing of overhead lines or sending and receiving electrical signals over the wire. With the grid connectivity modelling service, we are using existing voltage data to significantly improve the speed and accuracy of connectivity and helping utilities ensure high-performance grid operations and applications,” said Roberto Aiello, managing director of Itron Idea Labs.
“Enabling smart grid applications without accurate and timely knowledge of meter to transformer and phase connectivity is like finding your way with an out-of-date map. The grid connectivity solution is like the GPS, accurately tracking meter locations in relation to the transformers that serve them.”
Grid automation and repair
Itron states that its grid connectivity modeling service helps utilities quickly and accurately identify meter-to-transformer and meter-to-phase connectivity using hourly interval voltage data and sophisticated machine learning algorithms, without the need for expensive hardware or field labour. With accurate knowledge of meter to transformer and phase connectivity, electric utilities can enable a balanced grid and achieve better outcomes from their applications, such as outage restoration, revenue protection, load balancing, system planning, voltage optimisation and asset optimisation.

Grid Connectivity is a cloud-based offering that helps achieve this by applying algorithms to determine the precise connectivity from every meter to its distribution transformer as well as the feeder phase supplying the power. This helps utilities eliminate the substantial costs and risks associated with sending personnel into the field to trace the circuit of every meter to its distribution feeder as well achieve operational efficiencies and reduced truck rolls for unplanned outages.
