of Heathrow was fed from a single substation, as far as I could make out they say they're fed from three substations, and one was already out of action before the fire.

SSEN's report from last year on how much cable/transformer replacement was going to become necessary for that substation to prevent them becoming overloaded ...

Its confirmed... A blundering (presumably electrical) engineer! :-D

When I read the article it asked a question rather than making a statement.

Do you read from, "Is one blundering engineer responsible for crippling Heathrow?" that it was a blundering engineer, or just maybe?

As a general rule when someone uses a question as a clickbait title for an article, the answer is 90+% of the time "no".

would a French person interpret the annotation "22.000 kV" as

It's the Daily Heil so of course it's false. Questioning newspaper headlines are known as Betteridge's Law.

Somebody should have been checking the transformer temperature

and was the blunderer really an engineer? More llkey a rigger or an electrician

I should imagine most large transformers do have remote monitoring.

I don't know which of the transformers was involved, but at least two of them seems to have sprinkler/suppression pipework fitted, which I don't recall noticing anywhere before ...

and it also appears to have a concrete bund, presumably to contain any leaking oil or contaiminaated fire extinguishing media?

Only if the French person didn't understand that 1000's are represented by commas not full-stops.

In France 22,000 is 22 very accurately. The use of comma and full stop are reversed.

Some info about grid substations in general, from an engineer who works on them ... I remember hearing about Buchholtz relays that time large areas of London lost power about 20 years ago.

link does not work, I get the message:

"The video has been taken down for now until the investigation is further along and I’m allowed to comment on it again."

Works OK for me, and its very informative and interesting way better than the media bollix being put about!..

Ah! spoke too soon, obviously the poor bloke is being leaned on i reckon!..

He's replaced it with a more generic transformer video
