"An elevated moisture reading in one of SGT3’s bushings had been
detected in oil samples taken in July 2018. According to National Grid Electricity Transmission’s relevant guidance, such readings indicate ‘an imminent fault and that the bushing should be replaced’. While the
reading was recorded in National Grid Electricity Transmission’s online system, the mitigations appropriate to its severity were not actioned."

Hanlon's Razor applies again! Unless, of course, it was Russian
moisture... :-)

I hope customers and the suppliers learn that they need to have some understanding of each others roles instead of going for what I call
"sub system optimisation", which loosely translated means "optimising
our profits".

It's extremely strange. Whenever I have reported a network fault they
are out there like a shot usually.

My experience is that my electricity supplier is very good at short-term fixes but not so good at long-term fixes and checks for recurring problems.
We went through a phase of getting brief (*) 2-second power breaks every summer, especially after it had been windy. Sometimes they would happen
there or four in the minute, then there would be a gap and then another flurry of them. I diagnosed the problem almost immediately - overhanging
tree branches blowing in the wind, touching the high-voltage 11 kV or 33
kV lines and tripping a circuit breaker which either reconnected or else triggered a switch over to a different HV feed.
The electricity company always acted surprised, as if they would never
have expected this in a million years. One year the response was "well,
we cut back those trees last year. They've *grown* again." As if the
concept of trees growing was new to them. Another year they blamed it on
cattle using a wooden pole as a scratching post - plausible until the farmer who owned the field replied on the village Facebook group that
there hadn't been animals in that field for the whole year.
Strongly-worded letters to CEOs seemed to do the trick. The only power
cuts we've had since then have been planned ones that we've been
notified about in advance, and a long one after a violent storm that
affected a wide area. Those are understandable and forgivable, but brief repetitive faults are down to poor maintenance and not cutting back
branches *before* they get anywhere near causing shorts to earth.
(*) Just long enough that all computer equipment needed to reboot, and causing non-recoverable problems with our mesh wifi network which
sometimes locks-out some nodes if they are all turned back on
simultaneously - they need to be turned on in a special sequence
otherwise they stall as they try to auto-negotiate free 2.4 GHz wifi channels. I was considering buying UPSes - plural, because each node in
a different part of the house would need its own. That would need four
of them: three for "child" nodes and one for the "parent" node and the router.

That has the whiff of "different budgets", with the longer term one being bleed dry for the shareholders. (See also: water).
