'For example, when the phase detection impedance 63 is a capacitor method, when this impedance 63 is connected to a certain phase of the power distribution line F21, the power angle of the phase changes greatly after connection. "The following six are explained with specific examples. For example, the power distribution line F 11 system has a load of 200A (1320KVA / phase) and the power factor angle is 30 degrees later. The impedance for the false phase 63 uses a capacitor with a capacitance of 30KVA (KVAR). Therefore, by connecting the capacitor, the power factor angle will change from 30 degrees to 2 8.3 degrees. When the same conditions are used and the capacitor with a capacitance of 50KVA (KVAR) is used as the private phase impedance 63, its power is The factor angle will change to approximately 27 · 々 degrees.
