Design of Insulated Cables to Reduce Gassing Issues in Power Transformers

摘要

Dissolved gas analysis (DGA) during factory acceptance tests is typically used to help determine whether there are any thermal issues with a power transformer. While the insulated conductors within windings may be a major contributor to the gasses generated, there are other elements of the power transformer such as the insulated cables that are becoming more significant in the generation of gases - especially Carbon Monoxide and Carbon Dioxide.
