Transformer Oil - Transformers

Transformer Oil

An optical exchange window and reading unit is integrated in transformers to monitor the oxygen content of transformer oils. A system with excellent long-term stability (10 years shelf life), an oil tight fitting and tolerant to temperatures from - 40 °C to + 80 °C had to be built, so it would work in desert as well as in polar climate.
