Customization of length extension for cables
Length extensions for cables can be controlled in two different ways. Either so that a percentage supplement is made for each individual line or by adding a fixed value for each line that is created.
The percentage addition is controlled in the cablelength_percent.conf file and the fixed value is controlled in the FPP.ELCBL_ADD_LENGTH table.
If a line with nodes meets requirements for both percentage and fixed length extensions, the values are added.
Percentage control of length extension
The percentage extension is controlled by the cablelength_percent.conf file. The default file for this looks this:
# A file containing some additional percantage lentgh to add for cable/line distance. # # @author <a href="mailto:anders.nerman@digpro.se">Anders Nerman</a>, Digpro AB #
# All OH lines Feeder, service, street lighting, earthing [OH_lines] ctype.alllow=700100,*,*;700102-700103,*,*;700110,*,*;700112-700113,*,*;700120,*,*;700122-700123,*,*;700152-700153,*,* factor=1.02

# Allow customisations [include_cust_if_exists=cablelength_percent.conf]
|
In the file there are three sections that describe different percentage length extensions:
•Section 1 has a factor of 1.02, which means a length allowance of 2% of the total length of a line.
•Section 2 has a factor of 1.02, which means a length allowance of 2% of the total length of a line.
•Section 3 has a factor of 1.01, which means a length allowance of 1% of the total length of a line.
After the text ctype.alllow, the objects that must have the length extension in percent are described. The values that follow are: object type, subtype and component type. Multiple types are separated by a ; (semicolon).
Example:
ctype.alllow=700100,*,*;700102-700103,*,* |
This means that the object type 700100 (Insulated overhead line) and all subtypes and component types must be included.
The line also means that the object type 700102 (Feeder cable air) and 700103 (Free wire) and all subtypes and component types must be included.
If customization is desired, follow the steps below:
1.Create the file: cablelength_percent.conf.
2.Put the file under tomcat/webapps/bios/conf/app/el/cust_xxx where xxx stands for your customer name.
The file may look like this:

When upgrading the system, this file is overwritten. To simplify handling, it is suggested that the file be sent to Digpro and entered as your standard. This means that your customizations will be included in updates. |
Fixed value for length extension
The fixed value for length extension is controlled in the Oracle table FPP.ELCBL_ADD_LENGTH. The cables that are to have a fixed length extension are added to the table. The fixed length extension is obtained when they are connected to a certain type of node.
An example of table contents is shown below:

Explanation of line 12: When a Feeder cable ground (Otype_Line = 700101) for 0.4 kV (Subtype_Line = 2) is connected to a Network Station pole (Otype_Node = 702004) 20 kv (Subtype_Node = 7), there will be a length extension on the line of 1 meter ( Addlength = 1).
