Ute voltage between conductive parts when touched simultaneously by a person or an animal Note 1 to entry: The value of the effective touch voltage can be appreciably influenced by the impedance of the person or the animal in electric contact with these conductive parts.

[SOURCE: EN 50122-1:2011, 3.4.5, modified — "Whilst" was added so as to link the sentence "The time duration…" with the rest of the definition.] 3.16 low resistance fault fault condition where the resistance of the fault is sufficiently low that the fault current is of a similar magnitude to that which would flow if the fault resistance were zero Note 1 to entry: The resistance of the fault is typically dominated by the resistance of the power arc. Note 2 to entry: In this definition, resistance will be understood as also being impedance for AC fault currents. 3.17 high resistance fault fault condition where the resistance of the fault is sufficiently high that the fault current is of a substantially different magnitude to that which would flow with a low resistance fault Note 1 to entry: In this definition, resistance will be understood as also being impedance for AC fault currents. 3.18 abnormal operating condition condition where the system is operated beyond its intended capabilities such that damage or reduced life expectancy can be anticipated 3.19 short-circuit accidental or intentional conductive path between two or more conductive parts forcing the electric potential differences between these conductive parts to be equal to or close to zero [SOURCE: IEC 60050-195:1998, 195-04-11] 3.20 current collector equipment fitted to a vehicle and intended to collect current from a contact wire or conductor rail [SOURCE: IEC 60050-811:2015 (CDV), 811-32-01] SIST EN 50633:2016

Note 1 to entry: Substation local backup also extends to switching station local backup where appropriate. [SOURCE: IEC 60050-448:1995, 448-11-16 modified — "Instrument transformers" has been replaced with "a transducer", the definition was reworded to make it more generic and the Note 1 to entry was added.] 3.34 remote backup protection backup protection located in a substation remote from that substation in which the corresponding main protection is located [SOURCE: IEC 60050-448:1995, 448-11-17] 3.35 circuit-breaker failure protection protection which is designed to clear a system fault by initiating tripping of other circuit-breaker(s) in the case of failure to trip of the appropriate circuit-breaker [SOURCE: IEC 60050-448:1995, 448-11-18] 3.36 tripping opening of a circuit-breaker by either manual or automatic control or by protective devices [SOURCE: IEC 60050-448:1995, 448-11-31] 3.37 direct over-current release over-current release directly energized by the current in the main circuit of a mechanical switching device [SOURCE: IEC 60050-441:2000, 441-16-36] 3.38 indirect over-current release over-current release energized by the current in the main circuit of a mechanical switching device through a current transformer or a shunt [SOURCE: IEC 60050-441:2000, 441-16-37] 4 System to be protected 4.1 Description The system to be protected within the scope of this standard is the electric traction system, within the limits set out in Figure 1.

The upstream installations are considered to be covered by the protection principles for general transmission and distribution systems, taking into account the following aspects at the interface: • protection coordination; • communication; • automatic reclosure; • direction of power flow (consumption and regeneration). 4.2.2 Rolling stock The interface between the electric traction system and the electric rolling stock is the traction unit circuit breaker. For internal faults within a traction unit (i.e. faults occurring downstream of the traction unit circuit breaker) the requirements of EN 50388:2012, Table 7, apply. SIST EN 50633:2016
