The Analysis of the Maximum Efficiency for Delivering load and Total Energy loss of an Electrical Transformer Based on 22 kV

This article presents an analysis of the maximum efficiency for delivering load and total energy loss of an electrical transformer. The electrical transformer in this case study has a rated voltage as 22 kV, rated apparent power 50 - 100 kVA, which can be operated with the electrical distribution system of the provincial electricity authority (PEA). However, this electrical transformer is composed a no load loss and a load loss, respectively. These losses directly influence to the efficiency and energy loss of 3 phases electrical transformer. As mentioned above, this article is shown to analyze the maximum efficiency by using the practical parameters. Moreover, the total energy loss of an electrical transformer is determined, because it can be transferred to the electricity cost.
