Investigation of Survival/Hazard Rate of Natural Ester Treated with Al2O3 Nanoparticle for Power Transformer Liquid Dielectric

Increasing usage of petroleum-based insulating oils in electrical apparatus has led to increase pollution and, at the same time, adversely affect life apparatus. This increases demand Mineral Oil (MO), which is on verge extinction and leads conducting tests natural esters. work discusses dielectric endurance Marula (MRO), a ester modified using Conductive Nano Particle (CNP) replace for power transformer applications. The Al2O3 CNP that melting point 2072 °C low charge relaxation time allows quench free electrons during discharge. blended with MRO (MO) different concentrations. measured properties are transformed into mathematical equations Lagrange interpolation polynomial functions compared predicted values either Gaussian or Fourier distribution functions. Addition indicates 0.75 g/L an 80% survival rate 20% hazard MO 50% rate. Considering interpolated values, they used identify MO’s optimum concentration produces better results. test result confirms enhancement breakdown voltage up 64%, kinematic viscosity lowered by 40% 110 °C, flash/fire points after treatment enhanced 14% 23%. Hence proves be effective against electrical, physical thermal stress.
