Hello, I am new to this site and thought I would give this a shot. All my experience is in low volatge DC circuits and don't have a whole lot of experience dealing with AC but I am trying to learn. My boss and I are working on an experimental generator with 24VDC input but AC output. He has it built and now wants me to run some tests on it to find out A) AC output B) AC current output C) frequency of AC output D) Watts output. So far I have had a reading at output as high as 600V but stopped increasing RPMs because I didn't want to damage the meter. I've got readings of VAC at given RPMs and I know Ohm's law so D won't be a problem but how do I find max AC current without plugging anything into it??? We've plugged a few light bulbs into a power strip and I can get current readings using the standard method of interrupting circuit but this doesn't tell me max current output, just the load, as I am sure you know. We aren't sure if we should plug a device into it without knowing what it's putting out for fear of damaging something. Can someone help?
