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