BRAZIL — WEG and Neoenergia performed transformer repair services at the Termopernambuco power plant with the objective of reducing maintenance required time and ensuring power generation availability.

Brazil’s largest energy distributor Neoenergia and the electric-electronic equipment company WEG have carried out maintenance services on a transformer at the Termopernambuco thermal power plant in Ipojuca in the north-eastern state of Pernambuco, in order to prevent power generation shortage. 

With a power range of 18 / 22 MVA and a voltage of 13.8 / 4.16 kV, the transformer makes part of the plant's auxiliary system. The repaired unit is expected to contribute to the safety and availability that the plant provides to the system.

“With this solution, we were able to reduce repair service time from an average of six months to 30 days since it was carried out on site. Another advantage was the possibility of gathering both the field and the remote expertise of our company and WEG, with full knowledge of the equipment, engineering background and technical qualification of the teams”, says José Luis Molla, Termopernambuco´s Deputy Maintenance Manager. 

Termopernambuco has capacity to generate up to 533 MW, with three turbines in a combined cycle system. This technology combines the operation of two gas turbines, driven by fired natural gas together with a steam turbine.
