I know these are old, 1970s so predate electronic manuals.
Anyone out there have an installation and operating manual for a Brush FV they would care to share?
Thanks
I have come across primary D, Y, YN etc and secondary d, y, yn, z etc. Similairly no problem with the clock hour, but...
So a transformer with dual secondary windings is specified as Ddoyn11.
D for the primary Delta
doyn ? what is this meant to signify for the secondaries.
11 for the clock...
