The integrity of the cellulosic insulation in power transformers is considered one of the most
relevant parameters that affects their performance and reliability. Electric faults, such as
short circuits, have thermal and mechanical effects that degrade the paper and can
eventually produce the end-of-life of the transformer. The evolution of the properties of the
paper insulation of a commercial continuously transposed conductor due to thermal ageing
was characterised through the degree of polymerisation and tensile testing. Failure initiation …
