EMO:Use of line conductor information in SFT

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 File

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

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
