<P>PROBLEM TO BE SOLVED: To obtain a power management system where the power of important electrical equipment is never cut off without permission, even if the use of the electrical equipment connected to the same breaker competes with each other. <P>SOLUTION: A control terminal 217<SB>1</SB>in a first power management area 202<SB>1</SB>, connected to a power management server via a communication network (not shown) grasps a current flowing in a breaker 213, and turns on or turns off each switch which is arranged in the middle of a path for supplying each electrical equipment 215 with power 211 so that it is within the range of the allowable current, along a priority set in the power management server. The power management server has remembers their use time zones stored therein separately for each power management server 215, and a first control terminal 217<SB>1</SB>issues a warning against the use which exceeds this. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
