New page

The behaviour of SFT constraints is now derived from information about the thermal characteristics of the lines involved. The information required by EMO to do this derivation is contained in two files, the Conductor Parameters file and the Circuit Configuration file

==Conductor Parameters==

The Conductor Parameters file contains information on the properties of the different types of conductors used in transpower lines. This is a csv file with a heading line and the following columns

{|class="wikitable"
! Column !! Meaning
|-
!Conductor Code
|
:This is the code used to identify this type of cable
|-
!Conductor Description
|
:a description, for reference only
|-
!Absorbivity
|
:Average absorbance, the proportion of incoming radiative energy that is absorbed over naturally occurring frequencies
|-
!Coefficient of Resistance
|
:The rate of change in resistance as temperature is increased
|-
!Resistance @20 C ohms/km
|
:Electrical resistance
|-
!Mass per unit lemgth gm/cm
|
:The mass or weight of the cable
|-
!Diameter mm
|
:Diameter of the cable
|-
!Emissivity
|
:Physical emissivity, which determines the rate at which heat is lost through radiation
|-
!Specific Heat Capacity Cal/g/C
|
:Physical heat capacity, the amount of energy contained in a temperature rise in the cable material
