Experimental Investigation and Condition Monitoring of Insulation System in Liquid Immersed Power Transformers

Abstract

Power transformers are an essential and expensive component of an electrical power system. Failures in transformers can prove catastrophic, often resulting in irreversible internal damage. Hence, monitoring them is imperative for ensuring that the electrical grid operates continuously and reliably. In recent years, there has been extensive research into transformer life management due to the necessity of operating the electric power grid under increasingly challenging conditions and the growing demand for electric energy newline
