Chapter 7 discusses the double earth fault and shot circuit current through earth. Branch short-circuit currents can flow through earth in the case of unbalanced short circuits with earth connection, i.e., line-to-earth (single-phase) short-circuit and double-phase short-circuit with earth connection. Single-phase short-circuits are the dominating fault type in power systems with earthed neutrals and are leading to the maximal branch short-circuit currents flowing through earth.
