<P>PROBLEM TO BE SOLVED: To calculate shares of a plurality of common users by the small number of measuring devices regarding electric power, a gas or the like. <P>SOLUTION: Integrating wattmeters 12 are attached to distribution switchboards 10 installed at each floor. The integrating wattmeters 12 collectively measure the electric power supplied through the corresponding distribution switchboards 10. In each distribution switchboard 10, breakers 11 for each use such as for electric lamps, for plug sockets or the like are installed. At the inside of each distribution switchboard 10, a display of a rated current or the like of a circuit branched for each use destination is used, and a share ratio of an electricity rate for each use destination receiving a supply of the electric power through each distribution switchboard 10 is calculated on the basis of a proportional distribution. <P>COPYRIGHT: (C)2004,JPO |
