From these dynamic study cases, it is shown that a damping resistor of 75 , which correspond to 10 times XC,the capacitor bank impedance, is adequate to avoid SSR during motor starting for low feeder load conditions.
Also,the control system will disconnect the damping resistor when the feeder current reaches 100 A for which the system damping is sufficient to avoid SSR. This will avoid unnecessary power losses during operation of the series capacitor.
