Electrical supply

[Kevan Marshall]

I am fortunate to have Electricity at hand on the edge of my plot, I presume that I can install three phase (single phase to house and three phrase to workshop), I want three phase for Solar panel capacity and for some of my workshop equipment, please find attached pictures of how electricity is run, hopefully three phase is available as I see four wire on the pole at the edge of plot and hope there are no issues, the power is fed from a main line via a transformer and comes back up the smaller pole which runs to my plot, after that it drops down to possibly two phase to feed another couple of houses!

That looks like a relatively small transformer.

DNOs love it when customers pay to upgrade their old kit.

Exactly the same situation as me by the look of it. That looks like a single phase transformer. It will need a three phase one. And of course a new big twin pole arrangement.

 

How many houses are fed from it? Less than 3 and you will pay for it all. In my case job was going to end up close to £20k. And the supply was close to its destination. Needless to say, wont be doing that.

 

Or are you in Ireland?

The three horizontal wires on the pole with the transformer are 3 phase 11KV

 

That transformer on the pole is probably about 50KVA  That will feed perhaps 4 houses max.  I can't see from that view if it is single or 3 phase.  Photograph it from the other side, are there 2 or 3 connections to the overhead lines?

 

The cables on the pole with the lamp post are 240V That is probably single phase at that point.

Thanks Dave, 

It feeds two houses and a small wooden holiday shack and the shack I am tearing down used to be connected to it, I’ll have to contact NIE to see what they say!

post a photo of the transformer from the other side so we can see the connections to it.

In case it helps. I once (business not private) had a quote for a new transformer required for our client's new truck garage. ie a lot of power needed. One of these big ones with a fence round it.

200k or so, I can't remember.

Because it had so much spare capacity we got the cost halved. This was negotiated by a specialist who does nothing else.

Similar size to the one near me (50KVA) It’s years old from 1960 something. It serves 4 houses from what I could determine from the drawing SSEN sent me. Fortunately we are on a different line that had been upgraded.

It is hard to tell from the physical size.

 

We are served from a 100KVA transformer.  A few years ago it failed.  They replaced it with another one half the size.  I asked the guys why are they fitting a smaller one and they said it is the same rating.
