Transformer maintenance at Swaziland Electricity Company (S.E.C.) : a critical investigation

Abstract

SEC being an electricity utility within the context of a developing country, Swaziland is faced with the multi-faceted challenges of providing electricity to the poor in remote areas, comply with environmental and international standards and sustain industrial and economic growth. These challenges require that limited resources be allocated to the upkeep of existing network elements. Transformers form the most expensive single unit of these. The critical investigation looks into the approach taken by the organisation towards transformer maintenance as well as the allocation of key resources for the effective carrying out of this function. Through structured interviews, network users and employees of the organisation provide vital information on the status quo of transformer maintenance as well as how it affects their work. Copper theft is a factor that could not be ignored as it compromises all efforts of network protection. The partial transformer maintenance policy of the company leaves a section of customers and network assets in complete neglect. This is an undesirable approach to looking after invested capital and customer service. The research recommends its amendment and the introduction of laws and technology to curb copper theft.
