How to calculate transformer size?

How do you calculate transformer losses?
Answer : Transformer losses are mainly classified into two types: **core losses** (or iron losses) and **copper losses**. Here's how you can calculate them: ### 1. **Core Losses (Iron Losses)**: Core ... + \text{Total Losses}} \] I hope that helps you understand how transformer losses are calculated!...
