Analysis of Magnetic Fault Current Limiter for Faults Initiating at Different Positions of a Current Waveform

Power System Faults may occur at any instance of the voltage waveform like the mean position or the peak position or at any moment in between. To protect all the connected load from the effect of a large fault current, a novel fault current limiting device has been proposed. This device is Magnetic Fault Current Limiter (MFCL) which requires no additional control/voltage for its operation. This paper shows a complete analysis of the working of MFCL under fault occuring at different positions of the voltage cycle.
