Leveraging Machine Learning for Phase Identification

January 21, 2020

Inaccurate phase connectivity information may cause several operational inefficiencies – for example, unbalanced phases that lead to significant energy losses and sharply reduced asset lifetimes. Traditional approaches to phase identification require either manual intervention or costly signal injection. These methods are usually infrequently performed. As a consequence, the phase identification can quickly become out-of-date. Using robust machine learning techniques, Itron’s Strategic Analytics group has developed algorithms to accurately classify meters according to their phase using voltage information readily available from AMI meters.

Itron’s phase identification is offered as a service, minimizing upfront cost. In addition, pilot programs are available for a limited number of feeders to allow the opportunity to evaluate the service’s accuracy and benefit to your utility.

The following has evaluated to null or missing:

----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
