Optimization and Protective Distance of Surge Protective Devices in Low-Voltage AC Circuits

摘要

Protection performances of surge protective device (SPD) in one-stage protection of low-voltage AC power circuits, depending on location of SPD and equipment under test (EUT) are analyzed in the paper. Obtained results can be used for determination of effective protective distance of SPD both in front of and after its location, and could provide optimization of surge protection.
