Actually being underground is safer. There are several factors to consider here:

>Near surface soils modify the incoming ground motion often resulting in amplification at the ground surface.
>Seismic waves are reflected at the ground surface resulting in constructive interference and higher ground shaking at the ground surface.
>Structures respond due to resonance resulting in amplification as we go higher in the structure.

So structures below ground, like subway tunnels, often have less intense ground shaking than structures at the ground surface. They are also restrained by the surrounding soil so they do not resonante as above ground structures. So in general the loading is a lot less.

A good example of the difference between below and above ground shaking was when the bullet train was in a tunnel during the 2004 earthquake. The ground shaking was small in the tunnel but increased once the train came out of the tunnel and above the ground surface resulting in among other things derailment.

Earthquakes aren't the problem with burying cables though. The issue comes from capacitance rise and planned outages.

Capacitive line voltage rise leads to high voltage on the receiving bus, and this is prolonged by issues like light loading and long length of line.

Second issue is line maintenance, have to dig up the wires for wash. Any lineman will tell you it's a hassle.

You have to wash the wires? That's weird. Like literally the metal cables? I don't see the roads being dug up that often.
>>
>>14944391
>Second issue is line maintenance, have to dig up the wires for wash.

I don't know about other places, but here they use sort of like a sewer system for all those wires and cables, not connected to the actual sewers, of course.
If anything needs maintenance, they just open a hatch, don't dig up anything.
>>
>>14944391
>dig up the wires
what the fuck
>>
>>14944463
You basically don't want excessively high voltage at the bus. They operate at a voltage the same way your computer, coffee machine, or vibrator operate at a specific voltage. The issue is, voltage is dictated by line loading and load drawn. If a line is lightly loaded, it stores power. It's capacitive. If it's heavily loaded, it actually goes the other way, it's inductive and reduces voltage at the bus. When you throw a line underground, it's insulator is no longer air, it's the earth, or plastic. Unlike air, earth and plastic can have some conductive metals mixed in. It's not going to ruin anything, but it will lead to higher energy storage. Lines are also typically bundled underground as well, and GMR increases the voltage. It gets even worse under water. Typically underwater power lines are DC to resolve the capacitance issue.

You do also have to wash the wires. Doesn't sound like much, but think of it like your car. Except you drive that car 24 hours a day, 7 days a week. It's going to get a little dirty over the course of a year or so. If you get dirt on power lines, it affects the ability of that line to transfer power. Also, with line loading changing like it does, it heats up and cools down. This causes it to expand and contract. That is physical wear on the line.

>>14944489
This is good, but wires won't be exposed underground. Again, washing would come far too often. You'd have to open up their enclosure, whatever it is.

I definitely agree with that. The power industry is extremely conservative in the states and I imagine that same conservatism is true of the power industry in Japan. They probably don't want foreigners working on their grid.
>What do you mean by this?
Most problems the electrical grid faces are usually beyond people's control, like weather events. Every once in a while though, it's caused by inaccurate load forecasts and sudden outages in areas of the electrical grid. This is what happened in 2011 with the blackout in San Diego. A line was being worked on, then it suddenly tripped and couldn't be returned to service. Basically, when stuff like that happens, work really sucks. Ever since that 2011 incident there's been a lot of "close calls" the public doesn't really hear about, and those "close calls" are the worst days to be working.

>Does this mean it's limited work out there? Or you have to work different times every week?
It just means rotating shifts. The desk has to be manned 24/7 and operators work 12 hours a day for 5 days a week, then you take like 2 weeks off. Long shifts suck but social games make it a lot easier. They don't require tons of concentration and you're generally "available" if something bad happens. Plus the control room is kept really dark and you're given a comfy chair to work. There's actually plenty of work out there for grid operators, it's just that handling high-stress situations doesn't come easy for a lot of people.

I don't know how it goes for Japan. I'm not informed on city code for earthquake prone zones (which have very different rules from where I live, which is primarily disaster free).

I mean technically any pole is at risk of falling if it is under significant enough duress. Japan most likely compensates for the earthquake-y nature and requires extra study wood and additional depth per meter height. I'm not a Japanese civil engineer.

They're all concrete actually. Too humid for wood. They make a lot of preparations on their utility poles, and Japanese people don't seem to care where poles and towers go like people everywhere else in the world. Their zoning pretty much let's them put stuff anywhere.

But the point is that if I get close to one of these lines if they fall in an earthquake, I'm dead right?

At least it would be quick. Be aware that even if it doesn't fall directly on you, there is something called step potential where electricity kind of pools on the ground, and you can be electrocuted even if you're a little close. Just stay really far away from fallen poles.

There are power engineers and there are grid operators. Grid operators don't need a degree, they just have to have NERC certification. Power engineers also need this certification to do certain things, but they can still do grid-related activities until they're certified. BC's balancing authority is BC Hydro, they're the ones that hire grid operators.

Here's the informational sheet on the exam you take to get certified: http://www.nerc.com/pa/Train/SysOpCert/System%20Operator%20Certification%20DL/2015_NERC_Exam_Resource_Materials_Final.pdf

This is just my impression, but it's actually having the Japan problem of too many old people and not enough young people to take their place, and just like Japan they're on the brink of having a crisis.

Actually it's more that if a person is wearing the right outfit and shouting orders, people are geared to just automatically assume that the person is legit.

There's a great example in the Illuminatus books where the MC used it to illustrate how most people will follow even nonsensical orders if given in a tone of authority: he stops several cars in the middle of traffic, shouting, "Bavarian fire drill! Everyone out! Stay in line!", getting the perplexed drivers to follow him in marching in a circle around their cars before then getting back in as if nothing had happened. The name itself is a reference to the old prank of a "Chinese fire drill", where the passengers in a car stopped at a sign or light all get out at once and get back in different seats.

This type of behaviour is actually what I'm referring to when I was talking about "avoiding attention." In this case, I'd be disguising myself as an electrical worker so that I could take all the pictures I want without being questioned by local busybodies who think I'm a terrorist.

Thing is, what I'm doing is actively deceiving people, which journalists aren't supposed* to do as routinely deceiving people to get the news debases your integrity. Some outlets have policies of firing and blacklisting journalists who do these kinds of things without prior approval. Prior approval is, of course, impossible to get outside of situations where deception is absolutely necessary to getting the story and/or not getting the journalist killed.

Either way, very interesting discussion Power Engineer-kun.

Electricity's become such a trivial thing in our lives. The lights always come on when we flip a switch, and they don't when the weather's bad. For some reason, at least in America in particular, we don't like thinking where that electricity comes from, so we disguise our power poles, hide power lines underground, and make them sort of "blend in" so we don't give them much thought. I agree that power lines ruin really pretty landscapes, because it's a reminder that humans are constantly interfering with nature. We generate power from coal that disrupts the Earth's climate and that's all really bad.

The truth is though that electricity has advanced society a great deal, and I just have a deep respect for the feat of engineering that is the power grid. A ton of work went into the power lines and stations that allow us all to live a better life than our ancestors. These generating plants cost the same amount as like 100 disneylands, and they work 24 hours a day. Thousands of people work to make sure I can post on /jp/ about touhou or kancolle. It's *fundamental to society* that the electricity stays on so I can do that.

All I started doing was asking why engineers and linemen did what they did. Why is there a pole here or there? Where does it go? Where exactly does my power come from? I just took pictures of the stuff and just asked what it was. You can google every part of a substation, and all that stuff just interested me. Breaker schemes and all of that stuff is beyond me, I admit. Mechanical relays are totally nutso, if you ever google that. Now computers do it because it's obviously way more reliable.

I think what impresses me most is how BIG it all is. A lot of these generating stations cost more than 100 disneylands but I pay like $20 a month to draw power from it.

How would one go about getting such a job? Are there any education requirements, or can you sign a contract agreeing to work for 'x' amount of time and be trained on the job?

Some of the dispatcher jobs are on-the-job training. Minimum high school experience. The higher-up-the-ladder grid operator jobs still only require high school education, but also certification. If it's a local utility, probably doesn't take much. If you want to work at a balancing authority or transmission operator, they tend to look for experience.

I work with a guy that was a lineman for something like 40 years then just worked his way up.

well it's actually attached to the eastern interconnection. What they have is their own regional reliability organization, which is FRCC.

Disneyworld is its own balancing authority, which means it generates power for itself, and could, in an emergency, sell power to other balancing authorities. They use natural gas I think, all I know is that they call the generators Ercot 1-3. They just got a solar farm shaped like Mickey too.

Comp Sci doesn't. And since EEs are hand-in-hand in how much love they get with Comp Sci.

Nope.
