After a week of testing with excellent results, the transformer station is operating in the Eragia area of Corrientes, Argentina. The substation will meet a third of the electricity demand of the city.
It took 26 years for Corrientes to put considerable work into developing a plan for energy project which would meet rapid electricity demand.
Transformer station Corrientes Este has finally started to work four days ago and seemed to have passed all the initial requirements.
Sergio Gutierrez, a specialist who came from Mercedes operated 500 kV Estacion Ibera, was monitoring the structure against a wide LCD screen that day. He will remain in Corrientes Este until a permanent operator replaces him.
The monitoring of the structure with a polygonal configuration at high voltage can also be seen in the room. Among the drawings of red, green, blue and yellow circuits, there are highlighted power lines, transformer and graph nodes representing switches and various outlets.
Furthermore, on the 42-inch monitor there is a list at the bottom of the screen highlighted in yellow. It marks each progress with a certain frequency and in a case of an incident has a protective response in 23 milliseconds.
The system equipment demands a large room with robotic closets containing various conventional cables, fiber optics and minicomputer. A few more metres to the back, there is a large shed with large capacity equipment arranged at two opposing walls.
In previous versions of transformer stations, total equipment was arranged in multiple rooms to save space.
The station will be permanently connected after the formal agreement is signed.
The total processing capacity of Corrientes Este will reach 100 MVA, about 40% of the maximum demand recorded in February 2013 and will be provided by two transformers.
