INVESTIGATION OF THE PERFORMANCES OF A PERMANENT-MAGNET BIASED FAULT CURRENT LIMITING REACTOR WITH A STEEL CORE

There is all increasing need in power system applications for fault cu rrent Limiter, to limit the fault current in semiconductor devices and switchgear. These fault current limiters must be reliable, compact an d inexpensive. This paper reports the result of an investigation of th e characteristics of a Fault Current Limiter (FCL) consisting of a ste el core and permanent magnet. Design criteria are presented. The FCL c haracteristics are simulated using a Tableau approach and the simulati on results have been compared with experimental result.
