Abstract

Selected results of a project, which aim at building up knowledge on diagnostics of power transformers at Ceylon Electricity Board (CEB) of Sri Lanka, are presented. This is obtained by making dielectric frequency response (FDS) measurements on large number of selected transformers as well as on insulation models. The data gathered are analysed and a database is formed
