How do I calculate carrying capacity?

How would you calculate current carrying capacity of the ACSR or AAAC conductor?

• Answer:

  * ACSR or AAAC or anything else, it does not matter. * Conductivity depends on resistance of material and resistance depends on resistivity of material and some other factors. * Resistivity of any material is generally constant term and depends on material. resistivity of alluminium and cooper is different. * General equation for calculation of resistance is: R= SL/A where, R=resistance of material S=resistivity of material L = length of material and A = area of material and now finally I = V/R where, I = max. current which can pass at given voltage and temperature V=voltage applied R=resistance of material as calculated above remember R also depends on temperature also and varies with temperature....so for large change in temp. you will have to also consider that factor.
