Luka Kovacic, Koncar Instrument transformers: Large scale implementation of biodegradable liquids transformers

Končar instrument transformers

This presentation is hosted by Luka Kovacic.

There was no thorough experience regarding instrument transformers filled with biodegradable liquids. This fact called for extensive dielectric and other types of testing to verify its insulation system. The prototypes which have been examined were filled with two different types of biodegradable liquids: MIDEL 7131 and Nynas Nytro BIO 300 X. Both liquids have been successfully implemented, thereby also creating a large base of accompanying results and experience.
