چکیده
The fourth rail transit is an interesting topic to be shared and accessed by the community within that area of expertise. Several ongoing works are currently being conducted especially in aspects system technical performances including bracket component sensitivity analyses on various designs. Furthermore, lightning surge study railway electrification significant due fact only a handful publications available this regard, transit. For reason, paper presents electrical performance Direct Current (DC) urban affected indirect strike. strike was modelled means Rusck model sum two Heidler functions. simulations were carried out using EMTP-RV software which included comparison polymer-insulated brackets, namely Cast Epoxy (CE), Cycloaliphatic A (CEA), Glass Reinforced Plastic (GRP) together with station arresters when subjected 30 kA (5/80 µs) 90 (9/200 currents. results obtained demonstrated GRP material has been able slightly lower its induced overvoltage as compared other materials, for case µs), thus serves better coordination arresters. This improvement also reflected recorded residual voltage energy absorption capacity arrester, respectively.

متن کاملMitigation of Transient Overvoltages Generated Due to Switching Operations and Lightning in Gas-insulated Substation (GIS) Without Extra Limiter
Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...
متن کاملEvaluating Rail Transit Criticism
This report evaluates criticism of rail transit systems. It examines claims that rail transit is ineffective at increasing public transit ridership and improving transportation system performance, that rail transit investments are not cost effective, and that transit is an outdated form of transportation. It finds that critics often misrepresent issues and use biased and inaccurate analysis. Th...
