Re: Initial setting for sync phase angle on an RSG
you can use a three phase variac on three phase power to create a variable
phase shift. A variac wired as a series inductor will also create a phase
shift, but it is a bit hard to figure out how much shift you'll get (since
the inductance of the variac isn't usually a handy nameplate number)
