<P>PROBLEM TO BE SOLVED: To attain size reduction of a distribution board. <P>SOLUTION: A load of a secondary circuit in a current transformer is set to a small value, corresponding to a case where a digital apparatus is connected with the secondary circuit. The need for additionally connecting a board is eliminated in connecting the digital apparatus, thus reducing the sizes of the current transformer and a casing for storing the current transformer. <P>COPYRIGHT: (C)2003,JPO |
