1.0 PURPOSE AND SCOPE
This procedure defines the equipment and system numbering schemes that are to be used
in Electrical Utilities (EU) and describes the logic encoded within its make-up. Data
associated with the equipment which is identified by equipment numbers will be entered
into an integrated database system for the purpose of pertinent and timely information
retrieval as well as the elimination of redundant data recording and storage.
This procedure applies to equipment for which EU is the custodian and has operational
control and maintenance responsibilities. Included is all equipment falling within one of
the following categories
Cables
Capacitors
Electrical Distribution Panels
Lines
Meters
Poles
Substations
Substation Buildings
Switches
Switch Stations
Transformers
Vaults
Relays
2.0 DEFINITIONS
None.
3.0 INSTRUCTIONS
3.1 Responsibilities
1. The Design Authority is responsible for equipment and system number per
MSC-PRO-20052, Design Authority Program.
3.2 General Requirements
1. Equipment within the scope of this procedure will be assigned numbers according
to the description in the attachments listed below:
