Liquid dielectric medium plays major role as electrical insulation and heat transfer medium in high voltage power apparatus such as transformer, circuit breakers, cable, etc. More than 100 years petroleum based mineral oil is used as liquid dielectric medium. Even though they have better insulating and cooling properties, there are some issues related with environmental aspect. By considering environmental...
In high voltage transformers, the liquid insulations are used as the insulating medium as well as cooling medium. For the past several decades, the mineral based transformer oil is used traditionally for the purpose of liquid insulations. In the environmental aspect, there are several disadvantages in the mineral oil even though it has better insulating properties. By considering the environmental...
