Electrical safety is a cornerstone of any well designed electrical installation One of the critical tests to ensure this safety is the Earth Loop Impedance Test This test measures the What is Earth Fault Loop Impedance EFL The impedance of the earth fault current loop starting and ending at the point of earth fault This impedance is denoted by the symbol Zs Why knowing its value important It
Where a fault occurs in an electrical installation a loop impedance test will verify that sufficient current can flow to operate the fuses or circuit breakers protecting the circuit that is faulty and crucially that they can be operate within a Earth fault loop impedance as defined by AS3000 refers to the impedance of the earth fault current loop that starts and ends at the point of earth fault Essentially it measures the ability of the electrical system to handle fault current during a
