Assessment of MOV Deterioration under Energized Conditions
Energies, 2020 Metal oxide varistors (MOVs) are widely used to protect electrical and electronic devices that are very vulnerable to surges due to the low insulation level of the equipment. MOVs deteriorate gradually due to manufacturing defects, mechanical and thermal

Case Study about the Energy Absorption Capacity of Metal Oxide Varistors with Thermal Coupling
Energies, 2019 Metal oxide varistors are applied today inside modern surge arresters for overvoltage protection for all voltage levels. Their main issue is the thermal activation of their crossing current, which could lead to complete destruction by thermal runaway ...

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

Model Free Traveling Wave Based Fault Location Method for Series Compensated Transmission Line
IEEE Access, 2020 Locating fault position in a series compensated transmission line is a difficult task due to the non-linear characteristics of the metal-oxide varistor which is present in the protection system of the compensator. In this paper, a model-free two-terminal
