Power transformer failure management on the Eskom distribution network in Limpopo

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
