Thanks for that.

Thirded. But I really cannot stop myself quibbling about reactive "power",
though I suspect you didn't mean it.


The units of measure are volt-ampere-reactive.

To quote the instructor "reactive power sloshes around in the network,
between the load and the generator". The current flow makes some
of the conductors warmer as a result. It's not consumed as such.

"Reactive power - the delay between voltage and current at a given point - is
subjected to transmission constraints. As a result, it is often necessary to
produce reactive power close to the location where it is needed."

To carry reactive power, you still need the wire size for it. That's
the transmission constraint.
