New Fault-Location Algorithm for Series-Compensated Double-Circuit Transmission Line
IEEE Access, 2020 This paper proposes a new fault location algorithm to accurately locate the faults of series-compensated double-circuit transmission line and improve the stability of power system operation, which is not affected by fault types. The proposed algorithm is

Superior performing nano‐enabled metal oxide varistors [PDF]
International Journal of Ceramic Engineering & Science, 2019 AbstractCommercial metal oxide varistor devices are subject to nonuniformity, defects and coarse grain size, low working voltage, high leakage current, and mechanical cracking issues. This work tempted to make use of nanopowders and alternative sintering processes to achieve uniform microstructure and superior varistor performance.
