Symmetrical and asymmetrical short circuit

WebSymmetrical Fault types: Three-phase short circuit fault (LLL)– Three line of the conductor short with each other. Three-phase-to-ground fault (LLLG)– Triple Line-to-ground fault (LLLG)- A triple line-to-ground fault occurs when three conductors fall on the ground or come in contact with the neutral conductor. It is a symmetrical fault.
