Can Anyone Identify What These Things on the Power Lines Are?

[AlexStratus]

Anyone have a clue what these things are?  I have seen these globes on power lines in three locations in my area. In all three locations these are mounted on the two outer most wires and are placed above the roadway.  Two of these locations are within an eighth of a mile of house.
One set to the east and the other to the west of my house. Both sets are pointing toward my house.   The third is above the road about five miles from here, near another house that is located in the country all by itself.  There are two other power line crossing near this third location; however, no devises mounted on those other line crossings.  The globes on the power lines near my house were added to the power lines about three months after I moved here

possibly cell "towers". where in the world are they ?

Just guessing, but the description of the following type of device fits what I’m seeing in your photos. Size reference or detailed label/logo on the device might help further. Also, are you sure it's power and not telephone? That line looks insulated. I usually see bare wire aluminum power lines. Cheaper to make.

Energy Harvesting for Online Condition Monitoring of High Voltage Overhead Power Lines

Abstract
For electric power transmission, high voltage overhead power lines play an important role as the costs for power transmission are comparatively low. However, the environmental conditions in many geographical regions can change over a wide range. Due to the high voltages, adequate distances between the conductors and objects in the environment have to be ensured for safety reasons. However, sag of the conductors (e.g. due to temperature variations or aging, icing of conductors as a result of extreme weather conditions) may increase safety margins and limit the operability of these power lines. Heavy loads due to icing or vibrations excited by winds increase the risk of line breakage. With online condition monitoring of power lines, critical states or states with increased wear for the conductor may be detected early and appropriate counter measures can be applied. In this paper we investigate possibilities for monitoring devices that are directly mounted onto a conductor. It is demonstrated that such a device can be powered from the electric field around the conductor and that electronic equipment can be protected from the strong electric and magnetic fields as well as transient signals due to partial discharge events.

I think they are transformers or line indicators. Not sure though doing some research on it.

its something thats on every high voltage power line all around the world. i dont remember what it was but quite a long time ago there was some docu about people working on those lines on tv and they explained those things. nothing nefarious about them. funny how people suddenly notice something thats there for decades and think its some NWO mind control gadget.

Maybe its just something they used when they repaired something and left it hanging there. Or some damper to prevent oscillation when wind hits the cable. I thought it was that but the pics google spits out dont fit.

aaaaand where in this thread did anyone even elude to mind control ? he said the things were added 3 months ago, not decades, its usually best to read before making assumptions and jumping to conclusions.

the first thing that comes to mind is either a lightning arrestor or a marker to indicate a power surge.?

It looks like it could only serve as a secondary, single phase power meter. Being on a single conductor it could only be used to measure/total current going past that particular point. It'd be similar to a clip-on ammeter.

O those.... don't worry about those, you weren't supposed to notice that, look football is on... have some nachos here.... , how bout a cold beer? ill call you a stripper.

Damn if the NWO was only that nice.

In the second photo you see something like a 4 digit counter through the see thru dome. This would likely be used in concert with others (two -one on each line- before your meter and two -one one on each line- past that, etc)  to detect if an accessible (house) meter is not working correctly or if someone further down the line is stealing power.

Utilities are generally aware of the total power a main HV feed (before transformer(s)) draws from the system, so if the totaled billed metering from it does not tally with the total power consumption on it they need to find where the leak, loss or suspect tap is. In case of leakage or losses there could be potential fire or shock hazards (bad transformer or bad insulation). In case if an illicit tap it could be meter tampering, defective meter(s) or theft.

A clamp-on (totaling) recording AC ammeter is ideal to track down such issues, it need not be physically connected to the wire, but merely uses a laminated magnetic core that is "clamped" around it.  The magnetic-clamp core's own internal winding uses the wire's own magnetic field to "transform" the tiny magnetic AC eddy-current around the conductor to power itself/measure-accumulate the value of the AC current.

This doesn't necessarily mean they suspect you, it just means something like they have 20000 Kw/hrs going out and they are only billing customers for 15000 or-so. So they are trying to locate or figure out where/why/how the other 5000 are disappearing. They'll come back later and tally/compare all the meter records (over a testing period) to locate where this is happening. Having the "test" clamp-ons way up on the wires assures them that they can't be tampered with, and saves everybody the nuisance of having to have their power cut off to inspect/change all of the meters in the neighborhood.

The leakage might just be a bad insulator somewhere, but (more likely) it could lead them directly to some (power stealing idiot's irrationally huge) power hungry grow op.

If it turns out somebody just had a defective meter (or a salty leaking insulator is glowing cherry red all night somewhere  ) they'll have to eat their losses and replace it.
