dual supply from diifferent suppliers?

[mattysupra]

My local pub! The tills went down the other day but everything else seemed to be still running apart from half the kitchen!

They seem to be under the impression that half the electric (as on a boarder? ) is supplied from birmingham and the other supply is solihull.

so when one side has a power cut, one half of the pub stays running and the other half goes dead?
Does this sound correct or is the guy who came to fix speaking rubbish?

Surely it was just a breaker/MCB etc that hap tripped?

However the first spark that arrived said he cant fix it as its the other companys side!

Does this sound correct?

It's mad enough to be true!

I once worked for an electricity company, where the building had a substation at each end, supplied from different pylons.

Must have cost them a fortune, but it was intended to give minimal risk of an outage by not having a single point of failure. It was next to a now-disused coal generation building, which might be why there were pylons to spare.

The building contained some stuff they didn't want to lose power.

In the case of the pub, it is extremely unlikely. I would guess that the tenant's flat might have a different meter to the business premises, and could well be with a different supplier. I bet the electricity is the same though. There is a very slim chance that if they were on a street corner, and had different meters supplied from different streets, they might possibly have been on different supplies, but it generally isn't done like that. One town will be one network.

my guess, it's 3 phase and lost a phase somewhere along the street..

what's the name of the pub and where is it exactly?

if it's the parson and clerk then it's possible..

I know of one large commercial site that has feeds from two different DNO's at 11Kv to on site sub stations. The site is shared between the two feeds. If there is a loss of service from one DNO then the system automatically re-configures to bring all essential supplies to the remaining feeder.

Do the beer pumps still work
Beer no till
Sounds good to me

Yes!

But they dont know the prices so over charge you !

'Coljack' its the draw bridge pub in shirley/solihull.

it is very strange tho as one side of the kitchen stopped working and just the tills. But all the fridges, lights etc stayed working.

Is it not more likely that one phase of a three phase supply has failed?

 

[slup]

Oops... What ColJack said... I'll go back to sleep now!

I worked for one company where the 500KVA transformer was not big enough to cover the needs of the new building proposed and the DNO were very insistent that the two supplies never feed the same building.

But also worked where originally a load of small units were build in a trading estate one firm gradually bought them all and also built extra so it ended up with multi-feed points all three phase and all with there own earth connection which I was not happy with but it had not been supplied with idea of all being same building.

Having said that for a pub most likely as already said a three phase supply and fuse has blown.

 

[mattylad]

Sounds like it could be dangerous doing work there, chance of getting across 2 phases etc ?

Oh bugger
Thought it might be worth a trip down, for some FOCs

The best ale comes from hand powered pumps.......

We do work at a big mill which is fed from two seperate subs.

The main mill building has it's own substation, with all the offices and some of the warehouses etc being on a different supply altogether, but it is all one building, with some circuits crossing over into other parts of the building.

It is a nightmare to fault find on

To be sure it be true
Unless there freebies then I don't mind where they come from
