In case of single line to ground fault
Did you know?
WebThe ground fault may occur in three ways. 1. Single – Line-to Ground Fault (L-G fault) In a single line to ground fault, one live phase touches to ground. The fault current flows from the live phase to the ground. The other two healthy phases supply the fault current. 2. Double-line-to Ground Fault (L-L-G fault) WebMay 19, 2016 · Generally, single line-to-ground fault on a transmission line occurs when one conductor drops to the ground or comes in contact with the neutral conductor.
