    Classification of series capacitor compensation devices

    The location of the series capacitor depends on the economic and technical consideration of the line. The series capacitor may be located at the sending end, receiving end, or at the center of the line. Sometimes they are located at two or more points along the line. The degree of compensation and the. When the fault or overload occurs the large current will flow across the series capacitor of the line. Thus, the excessive voltage drop occurs across.
