The calculation of grounding fault loop impedance is stipulated in the Code for Design of Low Voltage Electrical Installations. However, it has not been widely paid attention to and implemented. As this provision relates to personal safety, the author hopes that colleagues in the electrical engineering design industry and construction industry pay attention to the calculation and measurement of grounding fault loop impedance of the TN system.
