ESO signed a Sandbox agreement and successfully tested Advangrid solution from Latvia. Advangrid is plug&play low voltage grid analysis equipment. DSO can setup and online analyze voltage quality in selected locations, it is easy to install and change monitoring location when needed. It provides automated reports for engineers.
During the pilot project, ESO identified a problem with the transformer when the client could not connect PV due to voltage fluctuations.
After the pilot total of 12 devices were bought by ESO and currently are successfully used by ESO technology and maintenances teams.
