Abstract This paper investigates the effect of different bypassing schemes and grounding methods on the secondary arc current and the transient recovery voltage (TRV) of series compensated transmission lines. It is known that in series compensated lines, the peak value of the TRV may exceed the insulation strength. Furthermore, a secondary arc current is generated during a single line to ground fault mainly affected by the capacitive coupling between the healthy lines and the faulted line and can persist for seconds. The steadiness of secondary arc current prevents line reclosers from having a prompt closing to fulfill the system stability. This paper discusses different scenarios that can be employed to limit the secondary arc current consistency and to suppress a severe TRV during a single line to ground fault. A frequency domain analysis is conducted to better understand the nature of the secondary arc current. It is noted that an accurate arc model based upon the Kiziclay’s arc model is used in the simulations.
