Smart Electrical supports KKS naming conventions for process-related identification of the following item types:
-
PDBs
-
Circuits
-
Loads
-
Converting equipment
-
Disconnect electrical equipment
-
Signal runs
-
Panels (control stations, cabinets, junction boxes, local panels)
-
Cables
In addition, the software supports point of installation identification for buses and cells.
For each of these item types, the following KKS segment properties are available:
KKS Level Name |
Property |
Description |
---|---|---|
Total Plant |
Total Plant |
Single character (numeric or alphabetic). |
System Code |
System Code Prefix (optional) |
Single digit. |
System Classification |
Three-character alphabetic key, selected from a standard list, that represents the type of system in use the plant. |
|
System Numbering |
Two-digit number with leading zeros. |
|
Equipment Unit Code |
Equipment Unit Classification |
Two-character alphabetic key, selected from a standard list that represents the type of equipment within the system used for measuring or monitoring the system, or the type of measurement circuit (level, flow, and so forth). |
Equipment Unit Numbering |
Three-digit number with leading zeros. |
|
Equipment Unit Additional Code |
Optional character (alphabetic) used for special cases such as a thermocouple with dual elements. |
|
Component Code |
Component Classification |
Two-character alphabetic key, selected from a standard list that represents the type of component. |
Component Numbering |
Two-digit number with leading zeros. |
|
Numbering Element (for cables only) |
Tag Sequence Number (non- KKS) |
Four-character numeric or alphabetic value representing the unique numbering of a particular cable. |
Examples
For a switchgear or PDB, only the System Code segments are required in most cases. Thus a suitable KKS name for a medium voltage PDB would be '1 0BBA01', where the values are designated as follows:
Property |
Value |
Description |
---|---|---|
Total Plant |
1 |
|
System Code Prefix |
0 |
|
System Classification |
BBA |
BBA MV distribution board |
System Numbering |
01 |
|
Equipment Unit Classification |
(Not used) |
|
Equipment Unit Numbering |
(Not used) |
For a motor, the KKS identification '1 0PAC01 AP001B –M01' could be used, where the values are designated as follows:
Property |
Value |
Description |
---|---|---|
Total Plant |
1 |

|
System Classification |
PAC |
Circulating (main cooling) water pump system |

You can change the terminology of a key on a project-specific basis provided that the contents remain unchanged. Make sure that you do not select a code that is designated as Blocked. Blocked coding letters are reserved for future technologies and new systems engineering configurations. They may only be allocated and released by the VGB Technical Committee on Technical Classification Systems.
