OILWATCH Transformer Laboratories is helping project developers and independent power producers improve the reliability of their wind farm transformers. These expensive and critical equipment items bolster turbine generator output from a few hundred volts to medium voltage distribution levels.
Pad mount liquidinsulated transformers are typically used on wind farms. However, they are usually rated as distribution transformers and not generator step-up units and this has contributed to their failure in these applications. In extenuating circumstances, a failure can result in explosions or fire that could damage property
and the environment, while also placing lives at risk. Moreover, load may be interrupted for protracted periods, depending on the extent of the damage which may involve either undertaking major repairs or replacing the entire transformer.
