Power outage

[Besoeker]

That can happen with concrete, steal, ect.

But lower probability, I suggest.
We have lived in our present house for about 12 years with zero outages. The last I recall was at our manufacturing facility over 20 years ago. That was because some pykies had nicked the copper for the earthing from our yard transformer. The utility shut off the supply while they effected repairs It was over the Christmas period so it didn't greatly affect production.

30,000 was the total for DTE out of 2,000,000 plus customers. About 20 to 25 customers on my block and several across the street lost power from this fuse. Most lots are in the 1/3 to 1/2 arce size, some at about 1, and one two larger. We are fairly well spaced.

Overhead lines are easier to fix than underground. Wood poles are just fine. Many last over 90 years. Poles in my area have been here 60 to 70 years.

I believe we are 4800, and wire spacing is good.

I believe those that lost power should have seen wild voltage fluctions as you suggested, possibly between 20 and 100 V on a 120 V circuit, but last night when I ask my next door neighbor, they lost power, if their voltage varied, he said no. But I don't know that he would perceive a variation. Several years ago when I lost power I saw the wild voltage fluctation. This largely results from motor over temperature sensing and reclosing randomly in different homes.

But more prone to failure.

Ahhh, ok, that makes sense then. BTW, all in all your system looks well taken care of.

I'd say very good, spacing is closer to 12kv then anything else.

Honestly, he may have no idea what you are even asking him. Also keep in mind that a slight drop in voltage results in a huge drop in light output in incandescent lamps.

Not by much, if a tree comes down so will the wires steal, wood or concrete. Also keep in mind car impacts, its better the base of the pole breaks free.

A falling tree is not very likely to affect cables in underground trenches.

True- unless the roots pull things up- but yes, I will buy this argument. And honestly with all the storms it will eventually be cheaper.

I suppose that's probably true. Aesthetics is possibly another factor.

Certainly. But- I have to ask you now: how do they control the added reactive power?

Added by what if I may be so bold as to ask?

The current carrying conductors being so close to the screen and earth.

The current carrying conductors being so close to the screen and earth.

And to each other. Normally that would reduce inductance.

Ah well, I suppose there’s a slight advantage to being disabled. If the powers off for more than three hours the power company has to provide a generator.

Are you disabled? I didn't know.
You're from Robin Hood country?

Sadly not here in the US. At most they won't cut the power if you qualify and have not payed the bill. In fact even if a hospital looses power usually they can't provide anything.

Yes to both questions.

Wife hasus looking at homes north of there.. up around peaks..lol... not too sure about that but she usually gets what she wants.

 

[Tony S]

I was up there last month visiting my son.

If she’s looking for a house in the Peak District National Park I hope you have deep pockets.

 

[Adamjamma]

not in the park itself//she is tossing about grays area near London or Manchester area... if it wasnt for her health I would just pack up and head south south west by a few thousand miles..hate snow of any sorts...
