1 Scope

This document specifies the basic voltages and test methods used in DC electric traction systems: This document applies to supply line voltages for DC electric traction systems under normal operating conditions: This document mainly applies to the following electrified transport: a) Electrified transportation of industrial and mining enterprises (including underground tunnel transportation); b) Urban rail transit, such as subway electric vehicles, light rail trains, trams, low-speed maglev trains, etc:; c) Urban trolleybuses, dual-energy trams; d) Suburbs (including satellite towns) and electrified railways of local railways: This document does not apply to: a) the rated voltage for representing or transmitting the signal (measured value); b) the rated voltage of the components or equipment units in the electrical equipment; c) Rated voltage of cranes, mobile platforms and funiculars: Note 1: The DC voltages involved in this document are average values: Note 2: The DC voltage in this document is the ripple-free DC voltage value: Usually, the DC voltage with the sinusoidal ripple content not exceeding 10% of the root mean square value is called "no ripple": Ripple DC":
