Actually they may have had (n+1)x2 or some factor like 2.
On big transformers is common to have oil pumps and fans on the radiators. So you can turn a 15MW tranny into a 30MW tranny (or whatever the manufacturer has calculated). Of course if you were already running the pumps and fans, then it doesn't help.....and you can't run them for too long, apart from the noise, things do like to cool.
Ah. So yesterday they were running at more like n+0.5, then n died and the 0.5 had to be fiddled with to get it up to n? Clearly the single transformer that was still operational when the Herald went to press this morning hasn't failed again, because I'm sitting in the affected area and my (non-UPS'd) home server is reporting an up-time that extends well into yesterday. So a margin less than 1 but greater than 0, and able to be extended to 1 in emergencies, makes sense. - -- Matthew Poole "Don't use force.
