Inductive fault current limiters: A review.

• A brief review is given on fault current limiter placement and its function in power system. • Reviewing of the magnetic structure and magnetic equivalent circuit of inductive fault current limiter. • Analysis of the imposed inductance of inductive fault current limiters during the normal and fault condition. • Extracting main features of inductive fault current limiters based on review and classification of inductive fault current limiters. • Presenting practical comparison among inductive fault current limiters. A fault current limiter (FCL) is an effective means of limiting fault currents that is a promising power system protection solution. This paper presents a comparative survey of research activities and emerging technologies of FCL and discusses in detail the features of an inductive FCL. Inductive FCLs possess superior performance and higher speed of operation in comparison with other FCLs. The magnetic structure of an inductive FCL is instrumental to superior performance. The review study discusses the feasibility and effectiveness of the magnetic flux based FCLs. In addition, the magnetic behavior of FCLs is discussed considering the analytical study of their equivalent circuits. Moreover, a comprehensive comparative study of inductive FCLs is presented based on their technical operational characteristics. [ABSTRACT FROM AUTHOR]
