Only thing I can think is dc series resistance from neutral? It was the end of the pole line. There is no egc. L1, L2 and neutral, gec #6 enclosure to a ground rod.
Yes, it is my opinion that a short will pull all of the voltages coming out of the transformer down.It seems to me that if L1 shorts to N, moving N and EGC in the direction of the L1 voltage, it would necessarily raise the L2 to N voltage.
I do not yet understand your argument that the L2 to neutral voltage will decrease. Unless you are assuming that both the L1and L2 voltage from the transformer will decrease because of a short on L1 only.
I will leave my copper water pipes disconnected from my service ground wire since it seems its a safer thing to do.
I second that.Do whatever you want but you are still mistaken.
Its surprising to me of some of the replys and theories as to what happened to me which was I stated in my original post. What part of "I'm 100% certain that one of my service drop hot conductors came in contact with my bare neutral conductor at the service drop" do you not comprehend?
Maybe this will enlighten some of you. Here is a link to Mike Holt, http://www.mikeholt.com/swimmingpoolbonding.php If you play this video #3 on pools from the 13 minute point on you'll see Mike Holt actually answers my concern about connecting the service ground to my copper water pipes.

Then you might as well get rid of anything with an egc bonded to a metal surface, because they would be energized too in your scenario- those bonded copper pipes are basically connected to the source (transformer) the same way that grounded refrigerator/stove/freezer case is thru the egc. Freezer case lights up in garage during this event, you touch it while standing on slab barefoot, you get bit.
Let's say this happened the way it did and the tranny fuse didn't open or some rarity occured, you know what? Thats a poco problem, not an excuse to do away w/ bonding. The professionals who responded here "comprehended" pretty well, and explained at great length/detail why this was highly unlikely.
I agree w/ the above that you are free to do as you wish, but that you are mistaken, and are making a mistake.
Is your W/H gas? How pure is your water?Theres no other way my copper water lines can get energized once I disconnected them from the service ground. So I have one less shock hazard to be concerned with.
If you are on a metallic underground water piping system that is common to other building, the other buildings can have faults that will energize your water pipes.I agree with your first two paragraphs. But at least I have eliminated one way of my family getting killed or shocked. Theres no other way my copper water lines can get energized once I disconnected them from the service ground. So I have one less shock hazard to be concerned with.

In my opinion given all of the types of faults that occur in or around a dwelling unit, unbonding the water piping system, increases the shock hazard.
It seems to me that if L1 shorts to N, moving N and EGC in the direction of the L1 voltage, it would necessarily raise the L2 to N voltage.

Not really. All you have done is make it a little harder to clear a fault it the water line becomes energized.I agree with your first two paragraphs.

Yes, and you might never know it's energized till you stand outside the home turning your outside water on or off.
rcmoon, you might try to remember these rules where developed over a 100 years by 1,000s of qualified people. Now you come along and think you know better. Do you not see an issue there?
Did you watch the video from Mike Holt that I referenced in a prior post? He clearly says its not a good idea to ground your plumbing pipes.

You are mistaken in what you think the video is saying.
This is what I suspected.
In my prior post it says #3 at the 13 minute point and beyond. Mike actually says its a terrible idea to ground your plumbing pipes and etc.
