<p>PROBLEM TO BE SOLVED: To speedily give information to a surveyor even if the surveyor is not on a center supervisory device side by comparing upper limit value/lower limit values, which area set, with supervisory information from an electric equipment and transmitting signal to a portable terminal equipment through a radio base station when supervisory information is out of a set value. SOLUTION: In a power reception/distribution equipment 11, power supervisory data of the voltage, the current, the power-factor and the demand power of a main transformer are measured in a measuring device 9, and they are transmitted to a central supervisory device 1 by wire communication I/F 5a and 5b. Transmitted supervisory are inputted to a supervisory data storage means 2 and they are compared with the upper/lower limit values of respective supervisory items, which are set by a setting means 4, in a comparison means 3. When power monitor data are out of the range of the upper/lower limit values in the respective supervisory items, warning output is outputted from the setting means 4. Then, a data output means 31 transmits warning data, the supervisory data and supervisory items out of the range of the upper/lower limit values to the radio base station 6 through wire communication I/F 5a and 5b.</p> |
