Abstract :
This paper presents the harmonics and inter-harmonics analysis of a passive magnetic fault current limiter (PMFCL). This device limits the current at post fault without affecting the pre fault state of the system. The harmonics and inter-harmonics estimation of a non-stationery signal generated by PMFCL ware investigated using Coiflet Wavelet transform and FFT. Continous wavelet transform (CWT) and discrete wavelet packet transform(DWPT) has been applied for estimation of harmonics and interharmonics in PMFCL under normal and faulted condition.
