Abstract :
Long distance EHV transmission and generator installations at remote locations have intensified stability problems. Transmission necessary to improve stability is expensive. Single- pole switching is being reviewed as an altemate. Phase-to-ground fault current in the open phase of the line is reduced by reactor compensation to make arc extinction possible. A means for increasing the line capability when one phase is open is investigated. The effectiveness is analyzed in detail using a digital computer.
