Özet:

 

The power transformer is one of the most expensive pieces   of equipment in a high-voltage AC power system. An adequate monitoring   system for power transformers can help in reducing the failure rate and   thereby enhance system reliability and economic efficiency. Long-term and   accelerated aging is not possible in real transformers, so prorated models   of real transformers are preferred. This paper presents a study aimed at the   aging of different cellulose papers and pressboards impregnated with   transformer oil subjected to accelerated thermal aging at an oil temperature   of 120 ∘∘^{\circ}C and winding temperature of 150 ∘∘^{\circ}C for time   intervals extending from 0 to 500 h. The study manifests a close   relationship between the degree of polymerization and the tensile strength   of paper and pressboard that could be used in predicting the condition of   solid insulation at various elevated temperatures. The graphical   representation of various solid insulation properties and their correlation   analysis has also been carried out.
