The substation brought a capacity increase of 300MVA to the interlinked system in the country\u2019s southern region.<\/p>\n

Trafo Equipamento El\u00e9tricos, traditional transformer manufacturer with plants in Gravata\u00ed, in the state of Rio Grande do Sul, and Hortol\u00e2ndia, in the state of S\u00e3o Paulo, supplied Itaja\u00ed 2 with three-phase, 150 MVA – 230 \/ 138 \/ 13.8 kV transformers with on-load tap changer, in addition to a real time monitoring system that allows remote and local access to transformers. This system is the first Eletrosul\u2019s transformer monitoring system.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]

<\/div>[vc_column_text]Trafo, after having assessed a number of specialist companies in transformer monitoring, selected 3 of them for a workshop where each one presented its respective system in details to the company engineers. Among the participants, Treetech was the only 100% national company. From the work done in this workshop, Treetech was considered the best-suited company to supply a complete solution \u2013 sensors and system.<\/p>\n

Specialist experience, aggregate knowledge and know-how of Eletrosul staff were added to the diagnosis and prognosis models of Treetech\u2019s Sigma Software, which due to its flexibility was able to accept and incorporate the new, client-specific analysis and diagnosis models.[\/vc_column_text]
