T_cave Posted March 30 Posted March 30 I was just driving 142065 with locomotive 186 134 on INT1, when I noticed that when the ED brake is active no amps are shown on the amp meter in the locomotive, whilst they are displayed on the HUD
SIMRAIL Team GoppelPL Posted March 30 SIMRAIL Team Posted March 30 They are lost on the resistors, as the E186 can't regenerate energy under 3kV voltage.
T_cave Posted March 30 Author Posted March 30 I'm confused, why does it then list how much energy was recovered on the trip summary screen if it's all converted to heat in the resistors?
SIMRAIL Team GoppelPL Posted March 30 SIMRAIL Team Posted March 30 Ooooh, now I see that you meant the display, where the amps should be shown, even though being directed to the resistors. As for the summary screen showing energy recovered, it clearly is a bug to be investigated 🙂

I’m honestly doubting that. Electrically they have all the components and circuitry they need. For AC operation they have a transformer followed by a bridge inverter that creates DC voltage feeding the traction inverters. For DC operation the transformer is bypassed/used as a line filter. There’s no reason why one and the same circuit that converts the intermediate DC to 16.7 Hz or 50 Hz AC during regenerative braking could not also create 3 kV DC. The reason why the DC/MS variants have brake resistors is that DC traction substations mostly cannot feed power from the overhead line back into the grid, so if one train were using regenerative brakes while no other train used up the power in the same section, the line voltage would rise uncontrollably.
