Default Open neutral

I recently lost the neutral between the pole pig and my meter. I had 67VAC on one side and over 160VAC on the other. I heard loud frying sounds as multiple surge supressors died, along with circuit breakers tripping. The break has. Been repaired, but I only have a couple working circuits. I lost my A/C and I only have a few working lights. I need to replace the service. I plan to move it underground. No Internet, phone or TV for almost a month now. The open neutral damage the CATV line when the neutral current was shunted through it. I have very poor cell service here. I hope that this gets posted. It was 98 degrees in my bedroom the other night. No sleeping in that. I had to take a nap in my truck with the engine running so that I could use its A/C.

You have my sympathy. That's both damaging and difficult to recognize in
time.

In my case the resistance to the meter grounding stake and buried water pipe
was low enough to keep the 'phases' balanced most of the time. I first
noticed a fluorescent light buzzing when the refrigerator started. Voltage
measurements showed a solid 240V across the phases and only small
fluctuations in the 120V.

I don't have two outlets on opposite phases close enough together to compare
their voltages with multimeters so I built a box with two analog AC
voltmeters (from Variacs) and power cords long enough to reach between rooms
whose outlets were on opposite phases (which I had mapped). It plainly
showed the simultaneous dip in one phase and rise in the other, to as much
as 180V momentarily when the fridge compressor drew starting current from
the other phase. Digital voltmeters may not respond fast enough to catch
starting surges.
https://theengineeringmindset.com/12...-phase-us-can/

The evidence that convinced the power company to replace the outside drop
and meter box was a clamp-on ammeter reading of 30A flowing through a water
pipe. They cleaned the neutral lug coming into the meter box, and when that
didn't cure it they replaced the weatherhead and meter box.

My long term monitoring solution is this meter that I boxed and wired to a
GFI-equipped outlet strip to display the load on my solar system inverter.
When not on solar power it shows the voltage and current of the appliances I
operate on the stove, like the coffee pot or slow cooker. It can check for
degraded wiring connections by plugging it into one side of a duplex outlet
and the 1000 Watt coffee pot into the other.

Poor soil and no metal pipes around here. Looks like at least a few thousand dollars to make repairs.

Probably way ahead of me... but if that was the Power Companys side
of the equipment they should be responsible for any damage caused by
a failure...

Not according to them. Some vines had grown up to them. They don't trim anything past the pole pig. The homeowner bas to do or have it done.

IMO you're in lawsuit territory now. Having the consumer maintain
anything around high-voltage wires is not what they promote in all
their public messages...

I was told that they will disco.ect your service for a day and drop the line on the ground so that you can remove trees and vines.

PPL electric around here, from the weatherhead on down is the
homeowners, service drop to pole is theirs.

I had an Anchor brand meter base fail, fixed it on my dime. BTW
Anchor meter bases have a 100% failure rate.

If one ground rod is not suffcient use two. Then they recommend
copper sulfate soultion to soak the ground or a large copper plate at
least 3 feet deep underground.

Grounding is difficult in many areas of Florida. Sand over limestone and dry. They repaired the drop, the real damage was indoors.

The good news is that your AC runs mostly off of 240 V, and all those
components (compressor, fan motors) should be fine. Probably the control
transformers are fried, that should be a relatively inexpensive fix.

Many computers and LCD monitors should accept anything between 86 and 265
V, if they don't have voltage selector switches. Anything with a wall-wart
will at least need a new wall wart power supply (if on the high phase).
