What's This On The Power Pole?

[coobie]

It is a line switch feeding the single phase tap.

From there the wire goes down to the vertical devise which is the knife switch/fuse [ poor picture ].

Yea, the pic sucks, wish I would have bought a good digital camera back when I had money. I do, however have a drone, and I feel a mission coming on.

It is pallet tracking device.

I thought that was classified!
It's only the antenna for a pallet tracker.
They have been doing a "catch-tag-release" operation on the wild pallets to more closely monitor their movements. The wild pallets essentially get an enhanced RFID tag.

If it's connected to the power line and ground, it's a lightning arrestor. See lower right of pic

On our power line there is protectors like this every house tap to prevent the transformer being destroyed by lightening.
This includes the protection on transformer. line switch.

Sure can tell the generation difference in answers . and to think this is our future leaders.

Since it is bell shaped and stood off from the pole, I'd go with the lightning drain thing. Not that lightning can't jump the distance to the pole...

What coobie said, it痴 a single phase tap. With a fused cutout on the cross arm.

I so wish I was with the co-op out here. My neighbors pay less than half of what I do for electricity. If I spent $12k I could get a line here, but I'll probably be dead before it pays off.

Sure wish I had that option.

Are you talking about the white dome shaped object? If so it's just a 25kv porcelain insulator. It's being used to support the phase (hot) conductor that serves your property. The oval shaped device on the crossarm is called a cutout. The skinning side of the cutout is the fuse barrel, which contains a one time use fuse. The single phase is tapped off the main 3 phase using a hot line tap, connects to the cutout, comes out the bottom of the cutout to the porcelain insulator and then over to the next pole towards your property. The wires below all that are neutrals. So the system that feeds you is a grounded-wye system. In my area of operation we run a 7,200/12,470 volt system. If you measure between the phases you with get 12,470 volts. If you measure from any of the single phases to the neutral you will 7,200 volt.

Yeah, I liked the pallet answer, but coobie is probably right, he used to be a lineman.

I like it... post your drone pics!

Can not be pertinent. I did not see anything in there about bug bats or pallets. :scratchchin:

Fuse that will burn out with high voltage(lightning) or can disconnect a service from main line power.

When it’s burned out it trips open and is easily seen. Usually replaced by linemen using a fibreglass pole.

:thumbsup: Winner winner, chicken dinner!

I think if it was a lightning arrestor it would need a ground connection (i.e. a wire running down the pole to ground).

It doesn't seem like anything else is connected to the bottom of the dome shaped object, but it's hard to tell in the picture because the low resolution capabilities of the potato that the picture was take with.

Yup, you are absolutely correct! I did by drone flight trying to get better images, but couldn't get close enough without making a spectacle of myself next to the highway, so I moved on to plan B, which was resurrecting my old Sony DSC-F828 digital camera which I kind of stopped using once my cell phones started taking better pictures...usually. Cell phones can't do 200mm optical zoom (and a bunch of other stuff) though, and that is what I needed here. So here's the pic that solves what was a mystery for me, and totally obvious for you even from a crappy picture.



I did do the drone flight, and although I failed to get the detail I wanted for the power pole question, while I was up I did a little panorama from about 50 feet, and a climb to 260 ft AGL. I thought you guys unfamiliar with what you can do with a $500 drone might be interested in seeing it. The drone is a DJI Phantom 3 Standard. I consider it's main drawback to be video quality and radio range which is only about 2000 feet, and less if you have a cell tower on your property desensitizing your receivers.

I didn't edit his video as much as I normally would and left in some transitions from one area to another like the landing approach. Here is a link to the YouTube drone video. DronePowerPoleHiDef.wmv - YouTube
