Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
It is harmful to Resonance Fault Current Limiter(RFCL) if bypass circuit refuse to work when fault come. Fault protection targer is to improve the reliabilty of bypass circuit. Control unit failure is the worst condition and its protection only depends on thyristor self-trigger which call Break Over Diode (BOD). BOD is thyristor overvoltage protection. If voltage threshhold of BOD is so low that action tiome will compete with judgement. If threshhold is so high that arrester of capacitor overvoltage protection will endure heat damage. The article introduces BOD operation sequence. Threshhold effect is analysed with action time and arrester energy. With simulation calculation threshhold effect rule is summerised and design numerical value is got.
