Coupled-Physics Based FEM Simulation to Conform Structural Integrity of an Earth Switch During Short Circuit Condition

摘要

Transmission and distribution of power has become a critical part of the modern power system. Transmitting power at high voltage decrease the losses in transmission line. With the increase in need for higher voltage transmission of power, the standards for designing such high voltage equipment has become stringent. Isolators, being one of the main high voltage equipment, is a challenge to design under such stringent standards. This is where virtual validation has gained an immense interest amongst isolator designers. It helps to predict the behavioural aspect of the equipment. Prominent research has been done in the field of exploring virtual validation as a distinguished tool for designing isolators. This paper deals with an FEM based simulation as well as the validation from practical aspects.
