Technical Approval of Electrical Power Asset Design

inactive
Organization: NR
Publication Date: 5 June 2010
Status: inactive
Page Count: 12
scope:

This specification applies to all design work associated with the renewal, enhancement and extension, including temporary works, of the following elements of Elecrtical Power infrastructure: TNO/DNO 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 activity, work carried out under emergency conditions, or renewals that do not require any alteration to exisiting infrastructure necessitating design changes.

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 a process for design approval.

The standard provides details of the process for Approval in Principle and Acceptance of Detailed Design that are required at key design stages of the project lifecycle (GRIP stages 4 & 5) through to confirmation that the installed asset is compliant to approved design (GRIP stages 6 & 7).
