Simulation and experimental study of power flow in a seven‐phase transformer under fault conditions
IET Generation, Transmission & Distribution, 2022 Fault analysis is necessary to design a protection system and circuit breakers for a power system network. The multiphase system is a new technology so very little work is found for the fault analysis of a multiphase system contrary, unlike a three‐phase
