A Comparative Study of Field Distribution Properties of Different Types of Oils Using Comsol

Nature ester oil is the alternative to mineral oil in transformer for cooling purposes. This paper mainly focuses on a comparative study of field distribution properties of three types of oil (coconut oil, peanut oil, sunflower oil) with different gap spacing values. The three types of oil have different conductivity and permittivity values. The electrodes are immersed in oils. The electrodes are made of copper material. The arc length versus electric potential graph is obtained. Using comparative study analysis we find out the oil which has the best field distribution properties. Electrical breakdown or dielectric breakdown is a cycle that happens when an electrical protecting material, exposed to a sufficiently high voltage, out of nowhere turns into an electrical channel and electric flow moves through it. All protecting materials go through a breakdown when the electric field brought about by an applied voltage surpasses the material's dielectric quality. The voltage at which a given protecting article becomes conductive is called its breakdown voltage and relies upon its size and shape. Under adequate electrical potential, an electrical breakdown can happen inside solids, fluids, gases, or vacuum. Notwithstanding, the particular breakdown components are diverse for every sort of dielectric medium. The electrical breakdown might be a flashing occasion (as in an electrostatic release) or may prompt a persistent electric curve if defensive gadgets neglect to intrude on the flow in a force circuit. For this situation, an electrical breakdown can cause calamitous disappointment of electrical hardware, and fire risks.
