Open 17+ pages maximum earth fault loop impedance table analysis in Google Sheet format. The value of Zin is determined by summing the impedances of the earth fault loop described in Section 3. The earth conductor size is determined with respect to earth fault loop impedance but also adequate short-circuit performance must be ensured by employing the adiabatic equation method from ASNZS 30081. 2008 for commonly-used overcurrent protective devices should not be exceeded when the conductors are at their normal operating. Check also: fault and maximum earth fault loop impedance table It should be understood that the reading obtained relates to the applied nominal voltage.
