In this paper, we investigate lightning return stroke electromagnetic fields and induced voltages on nearby overhead lines associated with an inclined lightning channel. The study is based on the Antenna Theory (AT) model, which is appropriately extended t ...
Air-magnetic circuit breakers are widely used for short-circuit protection in dc electric railways or industrial plants. The well-known drawbacks of these breakers are mainly a slow breaking action, a short lifetime, and high maintenance costs due to the d ...
Diesel - electric traction is a well established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel powered locomotive is due to the reduced costs compared to the infrastructure cost o ...
This paper deals with the assessment of the lightning performance of distribution lines, namely the estimation of the annual number of lightning-induced flashovers versus the critical flashover voltage of the line insulators. The procedure proposed by the ...
Diesel-electric traction is a well-established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel-powered locomotive is due to the reduced costs compared to the infrastructure cost of ...
Researchers from Switzerland and Morocco undertook a joint project to develop a technique for producing electrical energy from renewable primary energy sources to supply small networks of isolated consumers. Specific attention was paid to sustainable devel ...
The railway reforms introduced since the nineties tend to spread responsibilities among different actors involved in the management of the railway system. On the other side, the governmental organisations are forced to boost the productivity of their railw ...
