Total Earth Fault Loop Impedance Zs = Ze R1 R2 for TN-S and TN-C-S Earthing Arrangements How to calculate or measure total earth fault loop impedance for an installation connected to a TN-S and TN-C-S earthing arrangements. In this video I show drawings to aid with City and Guilds and EAL electrical exams at level 1, 2 and 3. The total earth fault loop impedance Zs of a circuit is made up for the impedance of the supply authorities cable Ze and the circuit impedance of the line conductor R1 and
