adiabatic equation - 2.5 2c SWA

Stewart Mason
I don't get involved with adiabatic equations all to often, hence I'm a bit rusty! I'm trying to calculate the R1+R2 for a 2 core 2.5mm SWA. Obviously the R1 is the easy bit, I'm struggling with the SWA as the R2.  I saw a link to a table on the old forum but I can't find it now. Any ideas?


Thanks Stewart

    Here's a R1+R2 table used to calculate the earth loop impedance using SWA armour for R2, (Zs), You can then calculate the prospective short circuit current and hence the adiabatic calculation.
