<P>PROBLEM TO BE SOLVED: To grasp a current consumption value at this point in time easily, and to avoid a system stop reliably. <P>SOLUTION: A current transformer 5 is provided for detecting a current flowing to an outlet device, and a current measurement section measures a current value at a control section 6. The measured current value is displayed on a display section 7, thus enabling a user to recognize present current consumption clearly. When the current consumption exceeds a threshold, the display color of an alarm reporting section 8 is changed, thus enabling the user to know the possibility of a system failure when a trouble occurs, and hence enabling appropriate measures such as the connection of equipment having a small amount of current consumption to be taken. An interface section 200 connected to a personal computer 9 is provided for setting an alarm threshold arbitrarily, thus performing alarm determination without depending on a breaker capacity, and improving the ease of use. <P>COPYRIGHT: (C)2007,JPO&INPIT |
