Abstract
Power transformers are the crucial part of the
power system network because they regulate the voltage
either up or down on the electrical network for safe use by the
consumers. Their reliable operation on the network is very
critical because it directly impacts that of the entire electrical
network connected to it. One of the major challenges power
utilities face is the failure of power transformers on the
distribution network. In this research, the dominating causes
of transformer failures on the Eskom distribution Limpopo
network were identified. Different power transformer failure
management strategies are discussed. The current
methodologies used in Eskom distribution to prevent power
transformer failures are evaluated. Different solutions to
improve the current transformer failure management
strategies are proposed. The defined methods are based on
literature and existing research on power transformer failure
management strategies.
