Modelling part of the Southern Region D.C. distribution network: Some electrical data (IM-ES-103)

Power is obtained from the national grid at more than 20 locations and distributed over a railway h.v. network to substations. Here it is converted by rectifiers to a nominal d.c. busbar voltage of 750 V or 660 V and fed via high-speed circuit breakers to top-contact conductor rails. The...
