Great this thread got bumped up.
I'm glad to share this obsession of noticing electrical equipment all over the place, sometimes to brass off the misses when I disappear into an alleyway during shopping to have a look at an old switchboard or meterpanel.
Also more than half of the holidayphoto's are usually of electrical equipment or trains if we are near a railway line.
I use the HT powerlines as a guide during travel too , also to see if I have missed a switching yard or substation station somewhere in my travels.
This is a great forum and it is great to see that I'm not the only one obsessed with an electrical defect.
The POCO industry keeps me busy with the real fire works.
