How to calculate R1R2 and verify Zs

Hi James thanks for the video help me a lot, one question if I’m using a 2 core armoured and the steel as the cpc how do I calculate my r1+r2.

Hi Dean, thank you for your comment. I'm glad the video helped.
When using swa as the cpc, it will be necessary to obtain the data from the manufacturer. Data sheets are usually available on the manufacturer's website, and I notice they include a value for the line conductor in ohms per kilometer. It used to be possible to get the value for the swa as well, but it may be necessary to contact the manufacturer and ask for a value for ohms per kilometer for the swa as well as the line conductor. This can then be used in the calculation I mentioned in the video.
Regards
James
