“…Description of the hysteresis curve [3] was done by means of harmonic spectrum of the measured no-load current as the input for subsequent Chebyshev transformation. As a result of this process it is possible to receive coefficients of the polynomial describing hysteresis curve (B-H characteristic).…”

This paper presents the harmonics and interharmonics analysis of a passive magnetic fault current limiter (MFCL). This device limits the current at post fault without affecting the pre fault state of the system. The harmonics and interharmonics estimation of a non-stationary signal generated by MFCL has been investigated using Morlet Wavelet transform and FFT. Continous wavelet transform (CWT) have been applied for estimation of harmonics and interharmonics in MFCL under normal and faulted condition.

“…These techniques all suffer to some extent from being complicated, expensive and difficult to implement. The use of permanent magnets to provide a cheap and simple alternative approach for magnetic offset in inductors has been presented by Mukhopadhyay et al [9], Dawson, Yamada and Iwahara [10], with specific tableau numerical methods introduced by Iwahara and Miyazawa [11]. More recent attempts have been made such as by Rozenshtein et al [15] separating the DC Bias and AC coils to improve the practical realization of the FCL.…”

Fault Current Limiters are used in a wide array of applications from small circuit protection at low power levels to large scale high power applications which require superconductors and complex control circuitry. One advantage of passive fault current limiters (FCL) is the automatic behavior that is dependent on the intrinsic properties of the circuit elements rather than on a complex feedback control scheme making this approach attractive for low cost applications and also where reliability is critical. This paper describes the behavioral modeling of a passive Magnetic FCL and its potential application in practical circuits.
