Electrical energy, explained
2020-11-10, 09:00–09:30, Main Stage

We all use a lot of power, but most of us never had the chance to actually understand the underlying basics of electrical energy when it comes to data centers.


Things you will take away from this: * What is capacitative load and why is it different from inductive and resistive? * Why is 3 * 230V = 400V? * Why do you need minimum distance between large wires? * Why is V * A != Watt? And why is V * A == Watt? Wait, what Watt? Wat? * How do you get a blacked-out datacenter back online after a complete power outage, just from diesel gensets?

Will copy later; need to update the blurb
