Hope I can make myself more clear, now.
I need two signal generators:
1 - Working both in the same frequency. When changed, both change at the same time.
2 - Each one with three outputs, 120º apart.
3 - One generator to simulate the output of the current transformers sensing the V in each pahse of a three phase generator.
The other would simulate the output of the current transformers sensing the I taken by the load from each phase.
4 - Phase difference between V and I signals able to be progressively altered from "lagging" to "following".
In the trade, genset is a quite common name given for AC generators.
Yes, my English is not good. I know that, much to my regret.
Let's say three phase.
