  • What is Power Transformer and How does it work?

    2020-1-13 · The power transformer is usually operated in full load because it is designed to have high efficiency at 100% load. On the other hand, the Distribution transformer has high efficiency when the load stays between 50% and 70%. So, distribution transformers are not suitable to run at 100% load continuously.
