Good morning, I'm a mechanical engineer with a MSc on thermal energy and I've graduated a year ago. Since then I've been working with industrial heat (sizing equipments, assessing efficiency in heating and cooling processes, etc.). I'm now moving to a new job involving energy efficiency in manufacturing plants (heat AND power) and I would like to learn more about industrial power networks (typical equipments, network structure, relationship with distributors, etc.) before I start in order to ease up my integration. I have only basic knowledge of AC and DC power and very basic knowledge of electrical machinery and electronics. I prefer SI units since I'm in Europe. Can you point out any resources on the topic (video courses, books)? Thanks in advance!
