Nanoparticle effects on the electrical and thermal performance of the transformer mineral oil

Mineral oil has been used as a dielectric medium in transformers for more than a century. The enhancement of its performance using nanoparticles (NPs) has been investigated by many researchers in the last two decades. Based on that, in this article, NPs were introduced to improve the electrical and...
