“…From this plot it can be seen that the interruption time T i guaranteed by the extra-rapid DC circuit breaker is in the range 10 ms ≤ T i ≤ 40 ms, depending on the fault current initial rate of rise dI F /dt. This range of interruption times, which is also compatible with the results of the simulations presented in [15], guarantees the safety of people.…”

In this paper the electrical safety of DC urban traction systems is analysed, with particular focus on fault current detection and on dangerous voltages which could arise in case of fault. For the discussion the tram network of Turin, Italy, is used as a case study. Firstly the structure of the DC traction power supply is described, analysing in detail the different components; then the safety of the system is analysed, examining possible types of fault. In particular, ground faults inside the substation and ground faults along the line are analysed in detail. Fault currents and dangerous voltages are calculated thanks to a simplified steady-state circuital model of the traction system. Finally, the consequent risks for the people are examined and some conclusions and possible solutions are presented.

“…The maximum allowed time duration can be compared with the interruption time T i of the circuit breaker, that in general depends on the prospective fault current and on the time constant of the circuit. A detailed analysis of high speed DC circuit breakers behavior is provided in [15].…”

DC urban light railway systems are used as public transportation systems in many towns worldwide. In these systems, short circuit currents are often similar, both in steady state magnitude and in rate-of-rise, to normal operation currents. In order to properly set the protection relays, to obtain short circuit discrimination and to avoid nuisance trippings, it is important to analyse short circuit and normal operation current patterns. This paper presents the results of measurement campaigns performed for this purpose on the tram network of Turin, in Northern Italy.
