Fault Location in DC Microgrids Based on a Multiple Capacitive Earthing Scheme
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 This article presents a new method for locating faults along feeders in a direct current (dc) microgrid using a multiple capacitive earthing scheme. During fault conditions, capacitors within the earthing scheme are charging by transient currents that ...
