163 A - 400 Hz CT Testing For Aviation Generator Application

SteveR:
Hi All,

What power supply equipment could I use to provide a 400 Hz, 163 A rms supply to support the testing of a wound Current Transformer installed to an aircraft power generator?

The test requirements are as follows:

"The assembly should provide a voltage of 3.45 as measured across a 10 ohm, 3 watt burden resistor, when a single turn primary current of 163amps rms 400Hz is flowing."

Thanks in advance for your inputs!

You could use two Fluke 52120A transconductance amplifiers in parallel driven closed-loop by a Fluke 5730A calibrator.  Or they can be driven open-loop by any calibrator with the result of a little less accuracy.  If you need this level of accuracy, then it won't be cheap.  What level of accuracy do you actually need here?

rvalente:
Check chroma and itest AC power supply, they often go up to 1KHz.

Maybe... using a big ass AB 10KW audio amplifier with an external current loop?

SteveR:
Many thanks for your reply, full requirements with tolerances attached.

Probably these specs was written in the time where big electrical machines were used. I'd says its a suggestion for a GPU (ground power unit) + transformer.
