Heathrow total shutdown

At the moment yes. It is why we still use SF6 in circuit breakers even though it is highly damaging to the environment as it is simply the best for the job.
The mineral oil has a few jobs inside a transformer, not just taking heat away from the cores. But being subject to arching in the tapchangers, so electrical breakdown. You also cannot afford to have any moisture inside a transformer due to the damage it can do to the windings. There aren't many substances that can do all of these things.

To be fair to Heathrow it seems like they've actually got things restarted pretty quickly considering the scale of the issue, listening to the Heathrow CEO explaining that they have 3x sub-stations and a backup transformer but getting all systems back up, running and tested takes time.

Surely this has to be the shortest A380 flight ever!

Saw a BA 747 go from Cardiff to St Athen in 2020 - massive circle over the Bristol Channel to go 10 miles down the road…

What a stupid place to put your backup in the same place as the primary power source. I guess it was built in the 70's or 80's where risk assessments never existed.
Then again we do seem to be backwards Britain now. Reminds me of this pumping station that was built to prevent the flooding of the A421 that got flooded.
A421: Work has begun to relocate a flooded pumping station
Work relocating a pumping station, that was submerged by flood water, to higher ground is under way.

It is and it isn't. It depends on the location of any transformers, switches and panels.
I've got my back up generators spread across our sites away from any subs though. Means multiple generators, smallest 60kva, largest 300.
Probably a good number of us have worked on or reviewed data centre power designs here. I can confirm we explored power redundancy to grid level and didn't have the same single point of failure as seen here.
Stop the discussion everyone, please submit your qualifications to @SDK^ prior to commenting or don't comment at all.

Forum full of people from technical backgrounds and he's shocked people know how power distribution works.

London Fire Brigade and the Met confirming that they don't believe foul play was involved in the fire.
Now I'm usually just a humble ships captain or an occasional aerospace engineer but my real passion is power grids.
Calm down !
I was referring to 'social media' not here
I'm 25 years working for National Grid and it's very interesting how people provide their insights/comments on how things 'should be done'

Certainly given Vlad and the boys food for thought on potential shenanigans though!
