Hitachi Energy’s provides an easy replacement solution for Polish utility

Poland, Lubliniec: Hitachi Energy has successfully designed a tap-changer with smaller dimensions than the conventional solution in the market.

Transformer manufacturer EthosEnergy has installed the compact three-phase star point tap-changers, part of the T-Sync platform for the first time enabling reduced dimensions for its transformer.

EthosEnergy core competencies focus on professional and comprehensive service solutions related to generators, transformers, turbines mechanical components and steel elements for power generation. The Lubliniec facility is located in the northern part of the Silesia Region, Poland. Ethos is producing transformers up to 500 MVA and 400 kV.

Electrical energy must be produced constantly at a rate that meets instantaneous demand. This is only possible with transformers equipped with on-load tap-changers to maintain a stable voltage level during dynamic loading conditions. EthosEnergy has now installed Hitachi Energy’s T-Sync on-load tap-changers and bushings in a new transformer for one of the biggest Polish energy producers.

“Hitachi Energy is our trusted business partner. For this project, we decided to order Hitachi Energy’s on-load tap-changer due to its high technical quality and short delivery timeline. The ordered component was made with great attention to high quality in a professional way according to required quality standards and norms,” said Rafał Maniara, Technical and Business Development Director from EthosEnergy.

The transformer will be in service from July 2022 making a positive contribution to business by optimizing the entire transformer. The smaller amount of oil and tank steel used to produce this transformer has enabled cost savings and a more sustainable design.
