Abstract

The core losses account for about 70% of the total transformer losses, which makes it a fundamental consideration when designing transformers. Transformer no load loss contributes less than 10% of the total losses of transformer. Even though, the no load loss is small, but it affects the transformer prolong capital investment. Due to this scenario, in this work, investigations on the core joint type are vital to see if there any possibility to reduce stray flux (due to air gap) that could reduce the transformer no load (core losses). Ansys Maxwell finite element base software will be the calculation tool.
