Hybrid Modular Multilevel Converter Family and Modular DC Circuit Breaker for Medium-voltage DC (MVDC) Applications
… proposed to ensure the balanced distribution of metal-oxide varistor (MOV) energy. The developed PEI achieves a peak power density of 7.4 kW/cm$^3$, much higher than the solution based on the IGBT modules. After integrating the developed PEI into a full-scale HCB, the breaking capability of the …

Fault Location in Series Compensated Transmission Lines
… unit, presence of non-linear element, i.e., metal-oxide varistor as a part of series capacitor protection unit and dependence of the existing fault location algorithms on zero-sequence parameters of the series capacitor compensated transmission line which cannot be estimated accurately. In …

Insulation-Constrained Design of Power Electronics Converters and DC Circuit Breakers
… the various components, i.e. solid-state device, metal oxide varistor (MOV), and their impact on the breaker operation. A 2.5 kV, 400 A SSCB prototype is designed and verified with experimental results to validate the design approach. Traditional MOV based voltage clamping circuits (VCC) used in …

Distance Protection Aspects of Transmission Lines Equipped with Series Compensation Capacitors
In order to meet the high demand for power transmission capacity, some power companies have installed series capacitors on power transmission lines. This allows the impedance of the line to be lowered, thus yielding increased transmission capability. The series capacitor makes sense because it's …
