Günümüzde, nüfus artışı, yerleşim yerlerinin ve endüstriyel alanların genişlemesi teknolojinin gelişmesiyle birlikte elektrik tüketiminde önemli bir artış görülmektedir. Buna paralel olarak üretim kapasitelerinin de artması ile güç sistemlerinde çeşitli sebeplerle meydana gelen arızaların sebep olduğu yüksek akım seviyeleri, sistemdeki elemanlar için tehlikeli durumlar oluşturmaktadır. Arıza ak...

Superconducting fault current limiters (SFCL) can be an alternative to conventional devices limiting short-circuit currents in power systems. SFCL use high-temperature superconducting tapes of the second generation (HTS 2G) SFCL, which, after reaching characteristic critical tape, go into resistive state (quenching), current. The determines moment activation SFCL. Therefore, its value should no...

A lecture on current limiter intended specifically for engineering students pursuing specialization with Electrical and Electronics engineering is proposed in this paper. The important information which doesn’t appear in text books are presented to the students. A general overview of different techniques of limiting fault current in electric power systems with special emphasis on two types of c...

Increase in power generation capacity of electric power systems has lead to increase in the fault current level which can exceed the maximum designed short-circuit ratings of the switchgear. All the equipment therefore must have a short-circuit rating capable to withstand this level. Short-circuit currents contain extremely high energy and can damage electrical equipment. Typically, the circuit...

Saturated-core fault current limiters (FCLs) are devices that have many applications and potential for use within power networks. At a commercial scale, these devices require high H-field magnets to saturate the steel core, which can typically only be achieved through the use of superconducting coils. Here, we present several challenges that arise in the application of superconducting coils in ...
