摘要： PURPOSE:To enable utilizing a power source such as a solar battery, wave activated power generation device and a wind power generation device which, for itself, is unable to continuously supply protection currents over a long period of time as a power source for corrosion protection without using a battery. CONSTITUTION:Change of potential to ground in the lapse of time after the shutdown of a protection current to an object to be corrosion-protected 1 is measured. Change of a protection current density to the object having slow change of the potential or the object in the lapse of time is measured. Electric protection to the objects are executed with supply of the protection current from a power source such as the solar battery 3 which is able to only intermittently supply the protection current to the object having larger drop of protection current density than a designed value. In such a manner, a battery and a charge-discharge controller, etc., are unnecessary and the system is simple to reduce the cost. Further, maintenance operation such as a periodic exchange of a battery for a new one is unnecessary and maintenance cost is reduced, too.

摘要： 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.
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.

摘要： PURPOSE:To improve a method for supplying a protection current. CONSTITUTION:Change of potential to ground in the lapse of time after the shutdown of a protection current to an object to be corrosion-protected 1 is measured. Change of a protection current density to the object having slow change of the potential or the object in the lapse of time is measured. Potential to ground of the object is measured to the object having larger drop of protection current density than a designed value is measured. Electric protection to the objects are executed with intermittent supply of the protection current by performing ON-OFF control by regarding a prescribed range of potential below corrosion protection-corrosion region boundary as a control range. When a galvanic anode method is applied, the extent of comsumption of the streaming anode is thus reduced and a maintenance cycle is prolonged. When an outside power source method is applied, the extent of comsumption of the outside electrode is reduced as the galvanic anode method, the maintenance cycle is prolonged and an electricity charge of the power source is also reduced.
