Hi guys a couple of weeks ago I was looking on Google maps to try to work out a future planned trip for when lockdown is done anyhow I went onto satellite view which is basically an areal view of wherever your looking at. Part of my search I saw an areal view of our local grid substation at chickerell on the foto there was what looked like very large cotton reels in the sub I was curious what they could be I hink they are very large chokes for voltage balancing there are also some square objects right next to them which I assume are capacitors not sure what voltage they run at but looks like 230/400 Kv does this sound about right? Incidentally I sorted out my rout for my future trip
I would guess that the "cotton reels" are air core shunt reactors and the rectangular blocks are capacitor banks. Could be used for a number of things but most likely voltage (reactive power) control of some flavour.
Not sure what the funky towers between them and the switch disconnectors are... I suspect that they're a little distorted by the image generation process (being tall towers with spindly details). By where it is I'd query circuit breaker arranged vertically but might be something more exotic.
Above my pay grade though so could be wrong on all of the above, but I do like being nosey at substations and would be interested if someone more informed had the right answer!
