    Power Transformers New Standards Are Officially Implemented

    On June 1, 2021, the new standard of power transformers (current transformer core ) was officially implemented. Transformers are basic equipment for power transmission and distribution, which are widely used in industries, agriculture, transportation, and urban communities. About 40% of the power loss of transmission and distribution is the transformer loss , which means it has great potential for...
