Abstract (en)
In this Transformer Supply, the Primary is supplied with 380V 50Hz or 440V 60Hz and to Secondary we receive inductively the desired voltage in spite of the difference of the frequency which exists at the Primary. The advantage of this invention is the industrial manufacture of such a type of a Transformer whose Primary to be supplied by 380V 50Hz or 440V 60Hz and at the Secondary of Transformer we receive the desired voltage irrespectively of the Primary of the Transformer being supplied by 50Hz or 60Hz. This invention is expected to have an enormous and wide application in the Industry and particularly in the Merchant Marine. <IMAGE>
