Summary
Assessing the Global Warming Impact (GWP) of transformers has become an industry trend. It is especially important in sectors with higher energy intensity and where stakeholders give value to sustainability aspects.
Read more Read lessDry-type transformers are equipment used in several industries where values such as safety for people, safety for environment, and low-maintenance are important and driving factors. It is typically the case for traction transformers, applied in rail transportation systems.
This work describes the results of an Environmental Product Declaration (EPD), based on Life Cycle
Assessment (LCA), which has been verified by a third-party company, to assess the GWP of a 1.6 MVA dry-type transformer for rail applications. CO2 equivalent emissions are evaluated for different stages of the transformer life cycle, and a sensitivity analysis demonstrates how the grid energy mix may affect the results. Finally, recommendations are given to the impact factors that influence the most each life cycle stage.
