Parametric Design Analysis, Cost Optimization and Lifetime Estimation of a Three Phase, 300KVA Recycled Electric Distribution Transformer

The cost of transformer losses and manufacturing can be minimized if transformer cost optimization is carried out when designing and producing. Transformer design, cost optimization and lifetime estimation are complex tasks that need technical know-how to be carried out accurately. This paper presents parametric design analysis, cost optimization and lifetime estimation of a three phase, 300kVA recycled electric distribution transformer. The recycled transformer has efficiency of 97.14% with maximum load efficiency of 96.98% and 3.68% of total power losses. The research work will be relevant to transformer designers, network operators, power engineers, field workers, researchers, Lecturers and students, as it exposes the transformer design analysis and calculations, cost optimization, lifetime estimation of transformers and their parametric models.
