You guys were so lovely and let me get post 21000, which I did not even realise when I put it up.
That was the post I asked be reserved for me when I kept this thread alive after exactly 12 hours from my previous post several weeks ago.

Originally posted by mee In the case of the power lines around here, the local power company crunched the numbers and determined it is more cost effective to keep putting up new poles and restringing some of them each time a major storm comes by versus burying the lines and avoiding any disruption for good. I'm at least glad they are now looking at the trees but that should have started long before the major outage occurred.
Apparently that was bad for business. Plus, the upside for them is, they can continually restore the utilities and look like a hero.
In Australia the companies crunched the numbers and worked out that if their powerlines cause a bushfire in a semi-build up area the negligence liability could be billions, and insurance companies would not give them cover at a sensible price, and they can just put up the price of power since there is nowhere the customers can get it otherwise, except the personally expensive and inconvenient self-generation pathway. And to cover themselves for people who choose to use mains power for just a little they charge very high 'supply' charges before the per unit sale of power. And the cost of certifying isolation of self generation from the external mains is very high, so leads to no power for people with solar cells when the mains fails, unless they go to 100% solar cells and have no mains supply. Summary, they do the work and pass the cost on. Electricity in SA cost me over 30c /kWhr. US students told me they could get it for about 20/kWhr.

It my be fool hardy, but I'm curious.
Or do they just tell me how disappointed they are in my lack of judgement?
I hope nobody faints and spills their beer or drops their cheese.
K-3 Kritters...
I'm waiting for the axe too fall. This might be the worst thing I've ever done in my whole life.
Surely such transgressions can't go completely unpunished?
It is obvious. You won't buy a K-3 because you do not need to in order to complete your collection of Pentax (front) branded products.

Originally posted by Racer X 69 Buried utilities can have their advantages, but:
Yes, installing power distribution systems underground is costly, 2 or 3 times the cost of overhead construction depending on soil, location, new construction or burying existing overhead lines in established neighborhoods, etc.. And locating faults can be challenging too. Then, once the fault is located, if the lines are direct buried, repairs require digging.
And people don't like it much when crews come along and dig up their front yard.
Early underground systems did have 'submersible' transformers. But they would ultimately start to leak, then short out. The utility I used to work for adopted the strategy of replacing transformers as they failed with padmount units, which sit on a concrete pad directly over the vault where the wires came and went.
Other equipment, switches and regulators also get set in padmount cabinets.
Some neighborhoods have covenants and restrictions, and the equipment is camouflaged like boulders and will have shrubs planted around them.
Like the electric service, the phone and cable only have the conductors buried, and all equipment is above ground. Stuff like that just doesn't hold up well in a damp or wet environment.
Finding faults in an u/g is not too hard, just apply a TDR box, measure the electrical length to the fault. Then get the documentation of the cables as laid, should get you within a reasonable digging machine digging accuracy of the fault.
Padmount transformers work well. The area I used to work had various covenants, but the law gave rights to certain service providers of utilities so they were partially exempted.
And the supply cables were laid on the road reserve, usually not under the pavement because that would be more disruptive and expensive to work, so landowners had no right to complain about digging land that did not belong to them. And, funny thing, if a landowners own power supply failed on property they usually had little concern for repairs being done, since it was direct help to them. Also, often owners had paid extra for conduit to enable preservation of their driveway etc.
When I redesigned the 19kV SWER power supply to Mantung (googlemap that) I specified adding 200m of overhead 19kV SWER (3 strands 12 gauge galv steel conductor) and a new transformer on one side of the street down the middle of the town. There was a phone line, overhead on the other side of the street which I showed on the drawing. Because of interference and safety issues we had to get SWER extension approved by Telecom. Got a phone call from their technician - the o/h phone line is not being used, there is an u/g line on your side of the road so that makes your proposed extension illegal. BUT our u/g line is there because when the contractor got there to put it in, instructions were the other side of the road, but the contractor thought your side of the road looked easier to dig. So my line now appears in streetview in GM. They moved the phone to the place it should have been.
A short time later the phone exchange was changes from one of the last Australian 7am-7pm Monday-Friday only manual exchanges to a 24/7 automatic exchange.

Try zooming during a long exposure. Very small aperture, f22, AND low ISO, 100 or less if available, and minimum scene lighting.
Sorry for the message that looks like a mighty tome. Must be something to do with the time of day here.
