In the global context of energy transition and industrial energy efficiency, reducing transformer no-load loss has become a key focus for the power industry, industrial enterprises, and commercial users alike. According to the International Energy Agency (IEA), transmission and distribution losses account for about 8% to 15% of total global electricity generation, with transformer no-load losses representing a significant portion of this. Whether you operate distribution transformers, power transformers, or dry-type transformers, optimizing no-load performance can directly lower your electricity costs. For facilities with transformers running 24\/7 \u2013 such as data centers, hospitals, and continuous production plants \u2013 the energy savings from minimizing no-load loss are particularly substantial.
