This video shows a typical scenario using infrared inspection of an overhead transmission line to identify a hot splice and then the proper correction of that hot splice using a ClampStar engineered mechanical shunt.
NOTE: At the 3:41 mark there's a mistake in the narration. He should have said 27 degrees Celsius, not Fahrenheit.
Most of the U.S. power grid was constructed 40-70 years ago. And connectors are the weak link in the system. ClampStar can be used to protect overhead connectors, effectively extending the life of aging overhead assets.

I have read a lot of comments asking how the pilot is able to keep the helicopter so still. Allow me to explain, as I am a seasoned pilot with over 30 years of experience. In situations like this, the combined weight of the lineman's and pilot's testicles helps to stabilize the aircraft.

david esktorp good thing I'm not a power line worker because then I'd bring 500 pounds of testicle

@jefffromjersey52 6 лет назад

That is the best technical explanation I have read yet .. thank your for that insight .. It seems that Periodic weighing of the testicles of both men is probably crucial in order to make any adjustments that may be needed on the Aircraft itself to fine tune the balance. ..

In another video, one of these helicopter-riding linemen says, "I've only ever been afraid of three things: electricity... heights... and women. And I'm married, too." :-) So yes, such workers have all the fears that one would expect them to have. But they learn how to over-ride those fears. "A coward dies a thousand times before his death, but the valiant taste of death but once.", to quote Shakespeare's play "Julius Caesar".

Being on a building and looking down, isn't the same as being on a helicopter looking down. The perspective to the ground is different. I noticed this when I went skydiving for the first time and you have to step out of the plane and put your foot on the wheel in preparation for the static line jump.

@Macintoshiba 6 лет назад

How many clamps before the Powerline becomes a Clampline?

@RobbieHatley 5 лет назад

Not going to happen. There are never that many splices to begin with, and most don't fail. Only the ones that _do_ fail (develop high resistance and hence high power loss and high temperature which shows up as white on infrared cameras) are clamped. The vast bulk of each line consists of segments of thousands of feet of unbroken conductors with splices between segments.

@robdevenney 6 лет назад

Impressive.... I know the lineman is probably safe with all the gear but still I imagine it takes some stones to do that job and amazing skill of that pilot. Nice work gentlemen!

@dunzerkug 6 лет назад

Nope, that gear will do nothing if the helicopter drifts too close to another phase and causes a line to line fault. Talk to people that have worked with transmission repair for a decade or two and they can probably name a person who died from that either form a bad pilot or a strong gust of wind. Sure they might fall to the ground after the fault but they are dead before they hit.

@christ2290 6 лет назад

Wouldn't there be a voltage differential across the bad connection? Heat is being generated because of voltage drop across the bad splice. I'm guessing the voltage drop wasn't high enough to warrant any bonding before attaching the splice?

@JohnAudioTech 6 лет назад

You are correct. According to Southwire's chart for that "Lapwing" ACSR cable is rated to handle 1354 amps max. Since the rest of the wire is cold on the IR camera, it is safe to assume current was much less than that. For example, lets say current was 400 amps and a guess for the heat dissipated in the bad splice was around 200 watts (it was warm, not searing hot), the voltage drop across the bad splice would have been 500 millivolts.

@mtcruse 6 лет назад

Was the black discoloration on the old splice caused by months/years of heat cycling?

@ClampStars 6 лет назад

Once the voltage drop across a connection reaches 0.3V (yes, that is 3/10ths of one volt!) the aluminum will exceed 650°C and the splice will melt. Actually, it is unlikely to get that high (0.3V) before the connector let’s go mechanically. If you can’t handle 0.3V, probably ought be in a different profession - and that would not include auto mechanic, as you would have to wear a full set of gloves and sleeves to change a battery!

Panda is basically right, no path to ground so no current flow. There is some voltage, but thus far, tests have shown no effect even on computerized helicopters. This is a MD500D. It was type certified in 1963, the D model in 1976. It has no essential electronics. The only electronics are radios and navigation equipment. You could start it and then remove the battery, and the entire electrical system and go fly. Its been done.

@qwertyFUBAR 6 лет назад

What about the specific scenario of the cable parting while the lineman is clipped on, with both ends suddenly heading away and down. Assume the clip is caught on something like the splice and hangs on. Does the wire between clip and helicopter have a breakaway accessory? A sudden tug would be notagoodthing.

I can honestly say I don't know of any story of who has died as a direct result of their work as a software engineer. I've worked on utility projects for 9 months now and have heard at least 5 different stories about linemen getting killed, 4 of those were doing hot work from a helicopter. The pay is better than most low end skilled jobs but the risk is very high.

DeWalt & Ryobi make flexible bit extensions. What if 10 drills were mounted on the platform, each connected in series and operated with a single switch, and each had 4-6ft flexible extensions.. Neat idea.

@djscrizzle 5 лет назад

@@Milosz_Ostrow For size reference, a 4/0 wire is just a bit under 1/2" thick. A 477MCM ACSR cable is about 5/8" across, while a 2000MCM cable is roughly 2 inches across... So, running into a brick wall is definitely a good analogy here.

@ClampStars 5 лет назад

ClampStars act as an electrical and mechanical shunt to prevent wire-down incidents caused by failing splices and other overhead connectors. If ClampStars are not installed and the splice or connector failed, the line would come down and possibly cause, things like; wildfires, electrocutions and other damage. Google "swingset electrocution" to see a video demonstration of a failed splice. Also checkout this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-u9xe273PFg0.html

@AuMechanic 5 лет назад

They should design a socket that is longer and has an angled slot out the side of it with an annular housing around it and bag underneath so when the head breaks off it stays in the socket then the operator just pushes it on to the next one which forces the broken one out the angled slot of the socket, into the annular housing with angle floor in it and tube down to the catch bag to catch all the heads. That way he wont need to invert the power tool each time to catch the broken bolt head out of the socket and put it in the can (risking dropping it) and can just go from bolt to bolt which would speed up the job, save fuel, reduce risk time near the line and the operator can just empty the bag of break off heads into the can after the job is done on the way to fit the next one.

How often do utilities run inferred inspection on all the conductors they own? Once a year?

@ClampStars 2 года назад

Hello Bill Zang, Thanks for the question. Most utilities will conduct infrared inspections on overhead transmission lines once per year or once every other year depending on the age of the conductor. Inspection requirements vary for each utility.
