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

What is Current Derating?
Every electrical component has a rated steady state current specified at a certain ambient temperature (in most cases 40 degC). This is the "continuous" current carrying capacity of the component at the rated operating temperature. If the actual ambient tempertature in the operating area is higher than the rated ambient temperature then the "continuous" current carrying capacity of the component is reduced. This happens due to the physical property of metals which causes the resistance of the matal to increase with the increase in temperature. Example: A component rated at 8A @ 40 deg C will be rated at >7A at 50 deg C. At 50 deg C you can still pass all 8A through the component but it will genenrate more heat and can eventually burn out.
What is an ammprobe?
Did you mean amprobe? In electronic engineering a current clamp or current probe is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows the electrical current in the conductor to be measured without having to make physical contact with it or to disconnect it for insertion through the probe.

What is skin effect?
<center> # 2 If the conductor is composed of one or more concentric circular elements, then the center portion of the conductor will be enveloped by a greater magnetic flux than those on the outside. Consequently the self induced back-emf will be greater towards the center of the conductor, thus causing the current density to be less at the center than the conductor surface. This extra concentration at the surface is known as skin effect, and results in an increase in the effective resistance of the conductor.

What affects a wires electron flow?
The size of the conductor is in direct relation ship to its rating capacity of carrying a current. The larger the diameter of the conductor the larger the amperage rating capacity of the conductor.
How can calculate the current capacity of 2.5 sq mm wire?
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.
How do you calculate the current capacity of a cable when the cable size is known?
The current-carrying capacity of a cable depends on a number of things in addition to its cross-sectional area; these include the type of conductor, number of cores, type of insulation, whether or not it is armoured, method of installation, etc. Accordingly, to determine its current-carrying capacity, you will need to refer to your national electrical code. For example, in the UK, BS 7671:2008 Requirements for Electrical Installations contains tables for all standard cable types, specifying current-carrying capacity, voltage drops, etc.
