**Show Us Your Installs!!!**

[Spudnik]

Right chaps,

Due to a few unavoidable issues, we have lost the original thread and pics etc.

Sorry about that!!!

So, if you want to re-upload your pics then great, if not, give us something new!


Cheers!!

Sort of. Thanks for coming and correcting and tidying my install for me to take this photo.

Half way through the job. I'll get the finished ones up when all the sub mains are dragged in and terminated.

No sweat mate how can perfection be improved:yes: I tend to get by on my natural good looks and sophistication. i did that install on a friday afternoon after 3hrs in the pub (not bad eh) I managed to get down 6 pints of fosters and 3 scotch an cokes and i was still able to put in cu and drive home. Amazing Stuff , i can sense the admiration from you even now:yes:

I'll add some pictures of a Job just being completed. The pictures are my snagging pictures so that I have a visual record of the snags etc and ensure the work is completed as per the program before my final report.

At last, a proper trefoil cable run! And a descent sized job to boot, what’s the MVA rating of the installation?

At last, a proper trefoil cable run! And a descent sized job to boot, what’s the MVA rating of the installation?

Thanks Tony, all I can say is that the total capacity is 14.7MVA running from 2 X 132kV feeders down to 8 11kV Tx's providing an A and B stream into the two structures so far built (which are only using some 2.7MVA). The rest of the capacity will be used by the remaining 2 main structures (4MVA each) (to be built plus a central Office block with a 0.5MVA capacity. The rest of the capacity is held for future use under ground)

Picture 9, is that a dual bus-bar sytem?

Yes Tony, two separate feeds from separate Tx's via individual Rotary UPS systems with auto changeover in the event of failure, and this is all backed up by individual LV Gen sets but the site also has 15MVA 11kV generating capacity in case we lost the feeds from the outside world..

Here are those other pictures I mentioned in email Tony..




Bear in mind these are snagging pictures so these are not finished items, all the cables require identifiers attached, including the HV or they need tidying in some way, but they are OK for what you need Tony.

The comms in the top 4 pics is the HV/LV monitoring/switching infrastructure that also runs the live mimic boards we have for ACB and MCCB positions and status

Now I’m retired I envy you.

Heavy power alongside plant control PLC programming were my favourites.

Nice to see this kind of stuff, it's well above the kind of stuff I do!! And it's nice to see people taking such pride!

And because I want to keep my last promise, that I will upload some more college-level ART! (Yes! I consider it art! )
Here are some 20mm A1 ring final circuit installation. The conduit is 20mm seam welded galvanised heavy gauge steel. And the sockets boxes are metal clud surface (MK logic+ I think). For the trainees like me: The A1 ring final circuit should have 2.5mm cable with a 32amperes BS60898 type B circuit braker, and it can potentially cover 100m^2 of space.
Oh I forgot to mention that we have a switched fused connection unit too.. But it does ΝΟΤ feed an appliance.



Sorry for any mistakes and thank you!

Couple of observations;

1. The layout of the conduit should have been considered so that they did not need to cross
2. Conductor length needs attention, if you look at one of the browns in the spur you can see where it has been rubbed when the faceplate screwed back.

I appreciate a lot comes with experience, but it's things like the scuffed cable that can cause you problems both in college and the real world, I would be none to impressed when testing a new install to find that.

From what I remember, they must cross as part of the assessment, and a large portion of the marks are dependent on your ability to set the conduit neatly

A couple of things.......

If you were to leave a little more length in the CU then you would be able to get the cables a little neater.

The fly leads in the accessories shouldn't be coiled

You do not really need the fly leads as you have cpc's run in and the conduit is earthed at the CU, and the back boxes are fixed lug. The only time you really need fly leads is if you have no cpc's and you are using the conduit as your means of earthing.

These are just pointers and are not criticisms!!, overall it's a nice install and a bloody good job compared to a lot of college work I see!

You have a point there High Tower, its been a very long time since I was at college, should have considered that!

 

[Engineer54]

I would be asking, why you have pulled CPC's into a galvanised conduit system in the first place?? All your achieving there, is filling up the conduit with needless copper!! lol!
