When mineral oil is exposed to aging processes during their operation, oil properties significantly deteriorate. This necessitates reclamation of the oil or replacement with a new one. Both solutions are not preferred due to their high cost. From this viewpoint, this study aims to enhance aged oil properties by using nanofillers to be suitable for reusing in power transformers. Accelerated aging test is carried out through heating oil at 120 °C in an oven for different periods of days. Under… CONTINUE READING
