<p><P>PROBLEM TO BE SOLVED: To provide a management system of a power distribution facility and a management method of the power distribution facility capable of measuring a contact resistance value at a connection point of conductors easily and continuously. <P>SOLUTION: A temperature sensor 9 is arranged at the connection point of a distribution line 3 and another distribution line 5 to measure the temperature at the connection point. A current sensor 11 is arranged near the connection point of the distribution line 5 with the distribution line 3 so as to measure the current of the distribution line 5. Furthermore, another temperature sensor 7 is arranged near a distribution board 1 to measure ambient temperature. The temperature sensor 9 calculates a difference between the temperature at the connection point and the ambient temperature received from the temperature sensor 7 and simultaneously receives a measured current value from the current sensor 11 to calculate the contact resistance value at the connection point. A receiving sensor 15 installed in an operation management room 13 received the contact resistance value and the measured current value from the temperature sensor 9 to judge whether or not they exceed specified values. A data-management/analysis computer 17 receives the contact resistance value and the measured current value from the receiving sensor 15 for the management of the trend of these values. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
