scope:

This standard covers forms used in electrical distribution, contact systems (conductor rail and overhead line), low voltage systems (eg signalling power supplies), protection and control systems, and general aspects of electrical power supply including terminology.

It is applicable to Network Rail staff and contractors using any such forms, as well as those drafting standards and control documents that refer to them. The scope of each form is described either within the form itself or in the associated documents (see clause 5 below).

Purpose

This standard provides the index and version control for standard electrical power forms. These forms are used to control a range of risks across the electrification and power asset base. In particular, their use will reduce the risks associated with misunderstandings by enabling consistency of data capture and terminology.
