Abstract

PURPOSE:The auxiliary winding is provided to magnetic core of current intrrupting signal transforemer for coaxial cable relay. And DC current is combined in adverse polarity between primary and auxillary windings. As a result, the whole size of the filter can be minimized, at the same time expanding transmission band.
