What is a Transformer Bushing?
In electrical engineering, the term "bushing" refers to a hollow electrical insulator that allows us to safely pass an electrical conductor through a conducting barrier without creating an electrical connection with it, such as the case of a transformer or a circuit breaker. Porcelain typically makes up a bushing. In actuality, however, a number of alternative insulating materials, including polymer, ceramic, glass, etc., might also be employed for the same function. When a substance possesses an electric charge, an electric field is created. Consequently, when a current-carrying conductor is positioned close to a material at zero potential, the field strength can increase to a very high value, especially in situations where the electric field lines are compelled to bend sharply around the substance. The bushing in this case regulates the size and strength of the electric field, which lessens the electrical forces acting on the insulating material. Transformer Bushing&#
