This module describes the controlled end-to-end processes when producing Isolation Diagrams and Instructions for the following:
a) 25kV a.c. overhead line equipment (OLE).
b) 1500V d.c. overhead line equipment (OLE) for Sunderland Direct Metro system.
c) 660/750V d.c. third rail systems (Euston to Watford; Merseyrail; and Northern City Line).
This standard is not retrospective and will be applied to all Isolation documentation including isolation diagrams, Instructions and DEP registers issued as of the compliance date of this standard.
Note: Where this standard refers to overhead line equipment / OLE it should be read as OLE and Conductor Rail equipment (CRE).
