Division 4.2.16.2 Pantographs raisedF1

Power consumption of the train (traction, auxiliaries and no-load current of the transformer) shall be brought to zero before entering the system separation section.

If system separation sections are traversed with pantographs raised to the contact wire, their functional design is specified as follows:

1. (a)

   the geometry of different elements of the overhead contact line shall prevent pantographs short-circuiting or bridging both power systems;

2. (b)

   provision shall be made in the energy subsystem to avoid bridging of both adjacent power supply systems should the opening of the on-board circuit breaker(s) fail;

3. (c)

   variation in contact wire height along the entire separation section shall fulfil requirements set in EN 50119:2009, clause 5.10.3.
