Power contact fusing currents for 7SP1 and 1SVAD8 contactors used in heating circuits of electric locomotives have been determined. It has been shown that in operation there may be situations when short-circuit currents are significantly greater than fusing currents. In this condition, a short-circuit current goes through the contactors contacts before protection actuation over a period of time long enough for the contacts fusion resulted from insufficient thermal stability current. Recommendations for thermal stability current values in the heating circuits have been developed.

Numerical simulation results for penetration of pulsed electric field following a lightning strike into a finite-size thin-wall cylindrical screen with various orifices are given. The solution to the problem is obtained by the means of two methods, namely, a finite element method and a hybrid method developed by the author. The simulation results are compared with experimental data.
