Cross sectional area of a protective conductors

OMS, and Mapj1, where do you learn such in-depth stuff?

I've havent ever worked on HV, or LV transformers, I have done a few connections to the LV side of the DNO transformer, always supervised by a DNO guy.

It would be nice to learn more about this side of engineering.

Thanks.

For me, it was the usual combination of education, training and experience - apprentice trained in a German company that had big involvement in mining and heavy industry so we were always pushing lots of power about the place - I went on and did a first degree in power engineering before moving into Building Services and doing a degree in mechanical engineering. I've been lucky enough to work in sectors where the size of the electrical infrastructure makes it similar to DNO and transmission networks anyway - for example I'm looking at a data park that soaks up the last 60MVA of 33kV  - and will be looking at another phase that brings in 300MVA at 132kV - other examples would be 80MVA intakes into airfields in hot and dusty places or 50MVA intakes in very remote areas to serve critical desalination facilities. Lucky enough to be in the right places I guess is the short answer


Not sure if courses are still running, and the qualification is more relevant to DNO staff, than those at the end of the network so to speak, but Aston University used to run a distance learning course over 6 or so modules that would get you a "Certificate of Competence" in Electricity Distribution - there were also single modules focused on substation design and earthing and a bit more detail on Power Transformers
