Abstract

A successful single-pole opening/reclosure procedure after single-phase faults in the EHV transmission lines requires parameters optimization for each transmission system. This paper shows the influence of transmission line transverse parameters together with reactive shunt compensation parameters in the reduction of secondary arc current after single-pole opening procedure for non-permanents faults. It is proposed a method to reduce the mutual coupling between phases in a three-phase system representation at fundamental frequency. Some simulations of transient overvoltage for different cases with optimized neutral reactors were performed with the ATP program.
