The transformer is one of the main components in the power network and transformer windings are one of the most expensive elements in the power transformer. Optimisation of winding distances is one of the most important parameters during the manufacturing of transformer. The distance between the windings in the two winding transformers is well known to transformer designers and manufacturers. However, insulation of the high voltage transformer with additional winding and tap winding is still a major problem for transformer designers. In this study, the additional winding to tap winding distance optimisation is made for a high voltage power transformer. Optimisation of the transformer's windings just not minimises the cost of the transformer but also increases the lifetime of the transformer. With additional winding and tap winding in high-voltage transformers, insulation distance is a major concern for minimising the cost and size of the high voltage transformer. In this study, an approach is made to balance the cost, size, and safety of high voltage transformers. The optimised distance and position between tap winding and additional winding are determined by using the finite element analysis. The finite element method results were also verified by making a prototype transformer.

变压器是电力网络中的主要组件之一，而变压器绕组是电力变压器中最昂贵的元件之一。绕组距离的优化是制造变压器期间最重要的参数之一。两个绕组变压器中绕组之间的距离是变压器设计者和制造商众所周知的。然而，对于高压变压器而言，通过附加绕组和抽头绕组进行绝缘仍然是变压器设计者的主要问题。在这项研究中，对高压电力变压器进行了附加绕组到抽头绕组距离的优化。变压器绕组的优化不仅可以最大程度地降低变压器的成本，而且可以延长变压器的使用寿命。在高压变压器中使用附加绕组和抽头绕组时，绝缘距离是最小化高压变压器的成本和尺寸的主要考虑因素。在这项研究中，采用了一种方法来平衡高压变压器的成本，尺寸和安全性。通过使用有限元分析确定抽头绕组与附加绕组之间的最佳距离和位置。有限元方法的结果也通过制造原型变压器得到了验证。
