What is this device on Home Transformer?
« on: November 21, 2015, 05:47:33 pm »

Was looking up today and noticed a device I don't recall seeing previously on the line transformer.
It is located in Madrid, a small town south of Santa Fe, New Mexico.Lightning is very frequent in NM.
The device appears to be more recent vintage than the transformer, anyone familiar with what it is, and why it was added?

It's logo looks like a stylized "S" followed by TE.

I couldn't find the specific product, but it look like a transformer monitor.  Probably monitoring internal temperature and pressure.

My guess is that it is an insulating shroud.  The thing to the right of it appears to have an insulating thing on it too, all of which is a bit unusual for MV distribution.

Having said that, the zone substation by my house has everything in the switchyard covered in some brownish stuff that insulates it, which I seem to recall was added to stop snow causing problems.  Though I cant see that being much of a problem in Sante Fe :)

Found the product page:

And here's a similar product in use in a utility substation:

It's an insulating shroud to prevent outages and damage caused by squirrels and other wildlife.

The strangest thing I have seen on power distribution is metal spheres on the HV cable in France.  I assumed they were some sort of lightning protection but don't know for sure.

This is the only picture I can find but those I saw were shiny and metallic.  http://previews.123rf.com/images/neko92vl/neko92vl1206/neko92vl120600064/14190405-pylons-and-high-voltage-lines-France-Europe--Stock-Photo.jpg

May be to keep the squirrels away from the fuse that usually ends badly for the squirrel and disrupts service.

Those are aerial marker balls so airplane pilots can see where the wires are and not fly into them.

Around here, I see them on high-tension lines near airports, over rivers, and other places where there are long, high spans between towers (such as over canyons).

My kids took one look and said it was for stopping squirrels and birds from getting fried. My dad had the power interrupted to his house when a squirrel jumped onto the transformer. That was one toasted squirrel.

Squirrels are responsible for many power outages. If those work they sure to show up everywhere.

Right now my transformers just have bare fuses hanging out there....

Jonathan,

Thanks, that's the unit. It was added sometime in the last three years, (I wonder when) here is a picture from before:
