GImpSI – Impact Management of Salinity in Insulations


The Project “GImpSI – Impact Management of Salinity in Insulations” started on November 2021 and has the goal to conceive a system that enables the monitoring and management of effects of salinity deposited on the insulations of high-voltage substations. Among other benefits, it enables the system developed to point out the ideal moments for equipment wash, which reduces risks of failures caused by salinity accumulation.

Other goals associated to the project are: to enable the effective management of effects resulting from salinity, to ensure operational safety and integrity of equipment; to enable the monitoring of the activity of corona discharge on equipment through daytime direct optical inspection, as well as its thermal behavior through thermography; to point out the correlations between factors that impact insulation performance, such as salinity, leakage current, corona discharge, thermal behavior and climate conditions (humidity, temperature, wind speed and direction) .

The coordination is carried out by INESC P&D Brazil and has the participation of Universidade Federal de Sergipe (UFS), involving Instituto Federal de Sergipe (IFS), Universidade Federal do Pará (UFPA) and Universidade Federal de Santa Catarina (UFSC). The research is funded by CELSE – Centrais Elétricas de Sergipe S.A, in the ambit of the ANEEL R&D Program.
