In OP you said you had the meter pulled - which we must assume means you had no load on your service at all. The voltage you were seeing is coming from somewhere on POCO side, you can't have voltage drop on neutral between the transformer and your service disconnect if you have no neutral load. You can have voltage drop on primary neutral and because it is bonded to the secondary that drop will show up on everything bonded to it.

That 1.7 volts is only .023% drop on 7200 volts - POCO will not notice a thing at that level.

I will relay this info to the homeowner in order to calm him down.

Thanks,
