Hi.
Cross country fault is usually responded to ungrounded or compensated grounded distribution network.
That means: one phase fault in one line ( for example A or R or L1) system is continue work, second fault in another bay in another phase, is phase to phase fault via earth happend.
Hope that help.
Best Regards.

Circuit to circuit faults. Circuits may be of the same or differing voltages, and same or different phase angles.
