simulate a current using an electronic circuit :-0

simulate a current using an electronic circuit :-0

(OP)
Hi I think I posted this in the wrong forum before, I think this is the forum I should have asked the question.

I would like to simulate a current. Also to do it using an electronic circuit.

I work as a test tech for an electric utility. There are times that I want to simulate current flowing in a device. Like driving a kwh meter with out having it installed in an actual ciucuit.

I know how to do this using a varyack  (adjustable transformer) by feeding voltage into the secondary of a CT. But I want to try it using an electronic circuit.

Someone in this post thread956-111849 said “audio power amplifier might be the most cost effective solution”. I'm looking to build something (or buy if its low cost) that I can use here in the shop.

Also want to learn how it works ( doing it using an electronic circuit ). Looking for plans or a kit or links on the web.

Thanks
Clark

RE: simulate a current using an electronic circuit :-0

You can use the Variac (not varyack) for the current, too. All you need is a resistor and a transformer - say 110:11 V (or 230:23 if in Europe). Make the resistor a little less than 10x(110/maximum current) and connect it between Variac and transformer primary, Connect kWh meter current coil to transformer secondary.
