I just learned about something called a "potential relay" to be used
in my 3 phase converter. It works as decribed above, when a voltage
increases past some trip point, it opens or closes its contacts. I
don't know if it would be fast enough to do the job. But I suspect
not.

BTW sorry about not referencing the author of the bit about "Plan B",
I used Agent as my email reader, and it looks like I haven't gotten
all the settings right yet.
