I hope someone here can provide me with some direction. I doubt there is much in the way of a commercially available test device that I could buy that costs less than I make in a year, so hope to build something, if possible.
I need to simulate a short-circuit condition where the current peaks at 18,000 amps, 277V, 60Hz for about one cycle.
I want to feed the output of this simulator into a UL489 breaker and allow the breaker to interrupt the circuit. I believe the UL489 breaker should open the circuit within 1/2 cycle...and that is ultimately all the energy I need to complete my test.
In order to limit the 'current limiting' effect the wire may have, I will connect to the breaker to my test device with just a couple of feet of large guage wire.
Can someone suggest what might be the most cost effective way to build a generator that can be reused up to about 100 times?
Thank you in advance.
