I wondered if anyone had experience with overbuild distribution circuits like 25 kV on top and 12.5 kV on the bottom. We've had incidents from tree limbs and from vehicle accidents where the upper phase makes contact with the lower phase.
Short of separating the 2 circuits (including putting one underground), the only other solution that comes to mind is to convert the lower voltage to the same voltage as the upper one. I don't know of any other solutions so that's why I'm asking what others do.
Thanks in advance.
