A novel arrangement for improving three phase saturated-core fault current limiter (SCFCL)
Arab Baferani, Mohammadreza; Rostaghi Chalaki, Mojtaba; Fahimi, Navid; Shayegani Akmal, Amir Abbas; Niayesh, Kaveh (Chapter, 2018)Fault current limiter (FCL) is a device that has low impedance in normal state of the power network and has simultaneous large impedance in the time of fault, so that it would lead to limitation of the fault current. Among ... -
Comparative study on various dielectric barriers and their effect on breakdown voltage
Forouzan, Elham; Shayegani Akmal, Amir Abbas; Niayesh, Kaveh; Lin, Jeremy; Sharma, Desh Deepak (Journal article; Peer reviewed, 2018)Non-pressurised air is extensively used as basic insulation medium in high-voltage equipment. Unfortunately, an inherent property of air-insulated design is that the system tends to become physically large. On the other ... -
