Page Count: | 13 |
scope:
This specification applies to all design work associated with the renewal, enhancement and extension, including temporary works, of the following elements of Electrical Power infrastructure: DNO/TNO incoming supply equipment, HV power supply distribution systems, HV and DC traction power supply systems and all associated subsystems, overhead and third rail contact systems, signalling power supply systems, points heating systems and all other fixed plant systems.
This specification does not apply to electrification and plant asset routine maintenance or testing activities, work carried out under emergency conditions, or project works that can be carried out solely within the parameters of the maintenance risk manual.
Purpose
The purpose of this specification is to control the risk to Network Rail's infrastructure and railway operations that may arise as a result of any changes to electrical power assets by mandating an engineering assurance process.
The standard provides details of the process for each phase of a scheme.
