The Type SGC relay is a static negative time overcurrent relay. It is intended primarily for the protection of generators against possible damage from unbalanced currents resulting from prolonged faults or unbalanced load conditions. The SGC features high sensitivity and dial selection of K setting from K = 2 to K = 40. A reset memory approximates machine cooling following intermittent negative-sequence overcurrent. The SGC comes in a standard M2 draw out case.
