DC Circuit Breaker Evolution, Design, and Analysis by Mehdi Moradian, Tek Tjing Lie, Kosala Gunawardane

“…These challenges require a fundamentally different topology for DCCBs, which are typically made using solid-state semiconductor technology, metal oxide varistors (MOVs), and ultra-fast switches. This study aims to provide a comprehensive review of the development, design, and performance of DCCBs and an analysis of internal topology, the energy absorption path, and subcircuits in solid-state (SS)-based DCCBs. …”

Effect of GIC neutral blocking devices (NBDs) on power network ferroresonance in Malaysia by Mohammed Khurshid, Zmnako, Ab Aziz, Nur Fadilah, Rhazali, Zeti Akma, Ab Kadir, Mohd Zainal Abidin

“…The simulation results found that the metal oxide varistors (MOVs) arresters in NBDs fault protection mode effectively clamped ferroresonance overvoltages below the protection level under faulty conditions. …”
