A portion of these power losses occur in the conductor windings due to electrical resistance and are referred to as copper losses. However, so-called iron losses from the transformer core are also important. The latter result from the rapid change of direction [...]]]></description> <wfw:commentRss>http://www.csanyigroup.com/transformer-heating-and-cooling/feed</wfw:commentRss> <slash:comments>7</slash:comments> </item> </channel> </rss>
