Define two open conductor fault.

When two phases of a balanced three-phase line open it creates an unbalance in the system and results in the flow of unbalanced currents. Such conditions occur in the system when one or two conductors of a transmission line are broken due to storms or if fuses, isolators, or circuit breakers operate only on one or two phases leaving others connected.
