摘要
A damping arrangement for thyristor switched capacitors in reactive power compensation systems. Large inrush currents are possible where capacitors are re-connected after a time of disconnection. The invention consists of incorporating in series with the thyristor switching bank a large damping resistor bypassed by thyristors which may in fact be a series part of the main switching bank. The bypass is opened prior to closing the main thyristors and closed a short time after thus encouraging decay of transients. The re-closing of the bypass may be done in stages (sections of the damping resistor) or progressively in successive cycles.
