<p>Provided is a method for appropriately installing a balancer in a three-phase four-cable power distribution system, thereby effectively obtaining energy at a low cost. A balance transformer (1) for reducing an unbalanced current flowing in a neutral conductor into a three-phase power line is installed in a line of the three-phase four-cable power distribution system having a three-phase power line and a neutral conductor as follows. A neutral line current in the line connecting the balance transformer (1) is measured. A capacity of the balance transformer (1) connected to the end of the line is calculated from a maximum value of the measured neutral conductor current and a maximum use voltage of the line. A balance transformer (1) having the calculated capacity is connected to the end of the line.</p> |
