Ageing of Crepe Paper in Mineral Oil and Natural Ester

Cristina Fernández-Diego;Alfredo Ortiz;Inmaculada Fernández;Carlos J. Renedo;Fernando Delgado

2020 International Symposium on Electrical Insulating Materials (ISEIM)
Year: 2020 | Conference Paper |
Several billion liters of transformer oil are used in oil filled transformers worldwide. These machines are voltage transformation devices in which during their operation the heat of windings and iron core firstly is transferred to the insulation oil and then to the cooling medium. Currently, this type of transformers mainly utilizes mineral oils due to their proven good service performance. Howev...Show More

Kraft And Diamond Dotted Paper Thermally Aged In Mineral Oil And Natural Ester: Mechanical Characterisation

Cristina Fernández-Diego;Alfredo Ortiz;Isidro A. Carrascal;Inmaculada Fernández;Fernando Delgado;Cristian Olmo

2019 IEEE 20th International Conference on Dielectric Liquids (ICDL)
Year: 2019 | Conference Paper |
Cited by: Papers (2)
Oil-immersed transformers, whose lifespan is defined by cellulose insulation's lifetime, utilize frequently mineral oil. However, this insulating fluid is being replaced by alternative liquids such as natural and synthetic esters. This replacement requires to guarantee a similar behavior of solid insulating materials immersed in them. Although there are different authors who have concluded that Kr...Show More

Impregnation processes of insulation rigid components of cellulose in synthetic ester and mineral oil

Alfredo Ortiz;Jaime Sanz;Severiano Pérez;Cristina Fernández-Diego;Ernesto Iván Diestre;Ismael Vela

2019 IEEE 20th International Conference on Dielectric Liquids (ICDL)
Year: 2019 | Conference Paper |
Cited by: Papers (3)
Although oil-immersed power transformers generally use mineral oil as insulation and cooling fluid, this liquid does not meet the new technical requirements of dielectric fluids such as high biodegradability, non-toxicity and high safety. For these reasons, natural and synthetic esters as alternative to mineral oil have increased their utilization in some transformers installations. Despite the fa...Show More

Assessment of the effect of commercial vegetal oils on Kraft paper ageing through mechanical characterization

Cristina Fernández-Diego;Alfredo Ortiz;Inmaculada Fernández;Isidro Carrascal;Carlos J. Renedo;Fernando Delgado

IEEE Transactions on Dielectrics and Electrical Insulation
Year: 2018 | Volume: 25, Issue: 5 | Journal Article |
Cited by: Papers (10)
Vegetal oils are considered a suitable substitute for mineral oil that is widely used in power transformers as insulation and cooling medium. Due to the fact that more and more power transformers containing this alternative insulating fluid are being constructed a mathematical ageing models is needed to help predict transformer failures. The continued performance of power transformers depends on t...Show More
