A dissertation submitted to the Faculty of Engineering, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science in Engineering / The sudden failure of oil paper-insulated current
transformers has become a problem of considerable
concern due to the cost of the resulting destruction,
and danger to personnel. The aim of the dissertation
is to determine the most suitable method of detecting
incipient faults in current transformers, test this
method on an experimental current transformer, and
finally implement this technique in a low cost on-line
monitor. A literature survey indicated that hydrogen
gas-in-oil on-line monitoring would be the most
suitable technique.(Abbreviation abstract) / Andrew Chakane 2019
