Grounding of feeder concentric neutrals
Grounding of feeder concentric neutrals
(OP)
Hello.
I'd like to know if there are standards, sketches or photos available for grounding of the outgoing feeder concentric neutrals (or tape shields, or LC neutrals) at the point where the feeder leaves the transformer substation and terminates on the riser pole. We currently ground the concentric neutrals at the pole to the ground rod but we are considering grounding them through 3kV lightning arrestors.
Thanks in advance.

If there is a separate neutral, then it could be left ungrounded, but there could be high induced voltages (the reason for the arrester).
