The compatibility tests between vegetable insulating oil and mineral insulating oil

2014 ICHVE International Conference on High Voltage Engineering and Application, 2014
Vegetable insulating oil shows good performance in electric, high anti-aging ability and environmental protection. Thus it is considered as a promising substitute for mineral insulating oil. In order to the wide spread application of vegetable oil in large power transformers, this paper designed the compatibility tests between vegetable insulating oil ...

New end life criteria for mineral insulating oils

2020 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2020
Mineral insulating oil manufacturing processes have changed significantly over the last twenty years. Oil base structures have also changed due to that, furthermore, the use of additives have also been improved. As a result, oil degradation kinetics is currently different, oil properties variation during aging must be re-evaluated. This paper describes

Space charge polarization in insulating mineral oil

2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013
Dielectric spectroscopy is a powerful tool to study dipole relaxation, electrical conduction and structure of materials. Space charge polarization, as a parasitic effect due to the blocking of charge carriers in the vicinity of electrode, can mask dielectric response of the sample at low frequencies.
