3 Phase rotary converters

Anyone have experience designing 3 phase rotary converters?

I'm building a 10 HP unit now, and have seen designs for self starting
systems that use a voltage sensitive (potential) relay connected between
the midpoint of the powered winding and the derived phase to disconnect
the start capacitors when the converter motor reaches full speed.

Can anyone suggest at what voltage the start relay should drop out?
I've seen specific part number suggested, but no actual voltage ratings.

Thanks in advance.
