    In some distribution lines,the voltage around the end of distribution line rises more than the regulation voltage. One of the reasons is the Ferranti effect caused by excessive amount of static capacity (SC) in high voltage (HV) consumers. In order to adjust the amount of SC, it is desirable to install the automatic power factor controller (APFC). However the APFC is not actually widespread, because its merit is not necessarily validated. In order to increase ratio of HV consumers installing the APFC, it is important to clarify merits of the APFC quantitatively. In the paper, from the result of measuring power factor etc.at receiving points in various HV consumers, the actual evaluation model of HV consumer is proposed. By using this model, the effectiveness of APFC is evaluated quantitatively. As the result, the reduction of electrical loss becomes about 2.0% of the whole electric energy in the feeder on the conventional distribution line.
