STUDY ON VERIFICATION OF TANGES DATES OF INSULATING OIL
The paper presents a study regarding the determination of the dielectric loss factor of the insulating oils at the filling of the power transformers. This study is complemented by: electrical equipment for determination of tg δ, mode of execution of the test, interpretation of the results. The purpose of this case study is to evaluate the electro-insulating state in order to standardize the apparatus and the adopted measurement methods in order to obtain reproducible results and to make a decision on replacement, refurbishment by filtration, drying.
