High Current AC Source
adam4521:
If the impedance of the thing you are testing is low enough, you could use a current transformer (eg 1000/5A secondary), connected in reverse. Years ago, I saw a switchgear manufacturer do primary current injection tests on busbar this way, although I don’t remember the details.
CosteC:
I use toroidal transformer with 2 turns of 250 mm2 secondary.
600 A for long time, up to 1600 A for short time.
Limit is in secondary thickness, but it is scalable. Output voltage is less than 5 V. Very simplistic yet not super stable as mains dependant.
