Abstract :Transformers are one of the important equipment widely used in the transmission, distribution, and power systems of electrical energy. An equivalent circuit can be created and losses can be calculated according to various operating experiments of the transformer. In the study, the variation of iron losses according to the voltage values applied to the primary circuit of the transformer was examined and a non-linear change in iron losses was observed depending on the applied voltage. When a load is connected to the secondary of the transformer, it has been observed that as the load increases, the iron losses do not change and remain constant depending on the load. The copper losses at various loads were calculated by increasing the load connected to the secondary transformer. It has been shown with experimental studies and calculations that copper losses show a non-linear variation depending on the load.
