Transformer is one of the cost effective and critical component in high voltage (HV) electrical system network. The quality of mineral oil is the key parameter to determine the health of the transformer. Globally, electrical and physical parameters of mineral oil are considered as the most primitive critical parameters for monitoring the transformer throughout the year. In this paper, electrical parameters like AC breakdown voltage (BDV), volume resistivity and physical parameters like flash point and fire point of new and aged mineral oil are analyzed by dispersing TiO2 nanoparticles in mineral oil under different vol.% concentration. It is found that, new mineral oil with TiO2 nanoparticles shows enhanced BDV compared with base mineral oil. In addition to this, volume resistivity, flash point and fire point also shows improved results with TiO2 nanoparticles.

Abstract


Transformer is one of the cost effective and critical component in high voltage (HV) electrical system network. The quality of mineral oil is the key parameter to determine the health of the transformer. Globally, electrical and physical parameters of mineral oil are considered as the most primitive critical parameters for monitoring the transformer throughout the year. In this paper, electrical parameters like AC breakdown voltage (BDV), volume resistivity and physical parameters like flash point and fire point of new and aged mineral oil are analyzed by dispersing TiO2 nanoparticles in mineral oil under different vol.% concentration. It is found that, new mineral oil with TiO2 nanoparticles shows enhanced BDV compared with base mineral oil. In addition to this, volume resistivity, flash point and fire point also shows improved results with TiO2 nanoparticles.
