Amorphous Transformer Contributing to Global Environmental Protection

INTRODUCTION THE electricity grid is an essential part of our social infrastructure, and with moves to protect the global environment gaining momentum internationally there is a strong need for environmental measures based on efficiency gains and other initiatives that make effective use of the materials and equipment that comprise the grid. The efficiency characteristics of amorphous transformers are dramatically better than those of conventional transformers and Hitachi is helping protect the global environment by working on a comprehensive program extending from materials development to the technologies used in these transformers. This article describes the background to the development of amorphous transformers and the benefits achieved by their use in Japan.
