Abstract
PURPOSE: To average the make/break frequency for all capacitors and thus to decrease the maintenance frequency by deciding the capacitor to be controlled in accordance with the operation frequency and the using condition of each capacitor.
CONSTITUTION: When the control is given, the capacitor to be given the make and break is decided by the status flag and the count table of memory device 4. In other words, the check is carried out at CPU for power factor value 3, and a comparison is given between the power factor of system 2 and the value of power factor setting value table of device 4. In this case, if the value is over in the capacitor insertion derection with throw-in of the capacitor, the capacitor which is not used currently is selected after checking the status flag. And then the capacitor featuring the minimum operation frequency is selected among those selected via the count table to give the make command. Thus the operation is averaged for the switch required for the make and break of the capacitor to disperse the deterioration of the switch.
