What is the expected efficiency rate of larger transformers?

Larger transformers are typically designed with high efficiency to minimize energy loss during operation. The expected efficiency rate for larger transformers often falls in the range of 98% to 99%. The correct answer indicates that a 98% efficiency is realistic because larger transformers utilize high-quality materials and advanced technology, which reduces losses attributed to resistance (copper losses) and magnetic losses (core losses). The design and construction of these transformers allow them to handle larger loads effectively while maintaining a very high efficiency.

In practical terms, this means that only a small fraction of the power is lost as heat and other forms of energy in larger transformers, making them extremely effective for transmitting electricity in power distribution and industrial applications. The high efficiency contributes to lower operational costs and improved system reliability, making them a preferred choice for many applications where large-scale power transformation is necessary.
