Merchant Job Training & Safety Program (MJTS) has been partnering with electric utility companies and electrical contractors construction companies across North America since 1983 to furnish them with the curriculum they need to provide their linemen a quality and comprehensive apprentice training program. Our program not only provides practical training for apprentice linemen, it serves as valuable skill advancement for experienced lineworkers, supervisory personnel, and anyone else at your company who regularly interface with your lineman crews. Among those who use and endorse our training program are private utilities, rural electric and municipal associations, and contractors.

Vector Diagraming Transformer Connections
Way too long…👎
It's sooo great to have a apprenticeship book revised last year, with links to videos recorded 40+ years ago, wow
Soooo glad I have to learn this, even though I will never use it!!! I'm not trying to be an engineer for a reason!
that video was 40 minnits to long
I missed my calling....
I want Turkish pls.
Dudes so good he’s erasing that Sharpie. Lol
why 360p
much beter explained than the fkng engineer who gave me my course of microelectronics and automation
Always what we gonna do 50 mins just to splice one rope? Seriously?
we are ropes factory in china , if you want import this kind plastic ropes , email me :bella.wang@@t whatsapp :+86 18205391765
See Captain & GiGi for 28minute version ( with shackle if needed). ruclips.net/video/RHhRx2RYwvY/видео.html#
Daming satsat
Very instructional and easy to follow. Thank you
Take 50 minutes to make a splice. Not for me.
Way to long, fell asleep twice, cut 35 minutes off and it might be good
e dopo 50 minuti e pure fatto male
sei lungoooo
Can we connect Dy1 & Dy11 transformer in parallel? give reason
I love you man
Excellent.
The "Pioneer Theory" states current flows in one direction, electrons flow in the other. I don't understand. a current of what? I always thought that the current was the flow of electrons. So if the electrons are flowing in one direction, what exactly is flowing in the other direction?
Aron, thanks for the question. Atoms are made up of (protons) positive particles, (electrons) negative particles, and (neutrons) neutral particles. In the pioneer circuit theory, protons flow in the circuit from the positive to the negative terminals of the power source. In electron circuit theory, electrons flow in the circuit from the negative to the positive terminal of the power source. The reality is that current in a circuit is comprised of flowing electrons. Protons have relatively large mass and they are tightly held in the nucleus of the atom. Electrons on the other hand are relatively light, and in conductors they are loosely held in outer orbits around the atoms nucleus. There are a couple of extremely good videos that are linked in the playlist that this video is in. The video was made a long time ago by GE. They are old and hokey, but they are great for anyone trying to get a handle on electricity. See "Principles of Electricity" Part1 and Part 2. ruclips.net/p/PLw-261nZGNp1ISrYG7-XCG2A_rfKP6n2_

He explains things so well! Too bad these videos weren't around back when I did Electrical trade school. I will definitely be showing my apprentices these videos in the future.
Are some of his practice problems available online? I really like the way he breaks it down!
I wish this guy was my shop teacher in high school. He really knows his shit.
This guy is....electric.
Set to 1.25 speed for better enjoyment of the video.
sei lento ooo
Thanks for the lesson, this really helped.
Awesome! I wish I got him as professor!
Dennis is very good lecturer, and explains things very well.
Thank you for an awesome video! :)
You're very welcome!
No, but seriously, you helped me save my school year :)
At 6:15, the explanation of the vectors and how they are tied is opposite from what is drawn on the board. The first example is of a subtractive transformer, so the vector arrows must point the same direction with H1 and x1 tied together (same potential) making the voltage measurement between H2 and x2 108 volts. The additive example begins around 7:10 where the vector arrows point opposite and H1 and x3 are now tied (same potential) to make voltage between H2 and x1 132 volts. Believe me, he knows his stuff, but is still human! Great videos for in depth learning.
+bbrown86neo thanks for the comment! I would like to suggest something though. Dennis always drew his vectors so that they point to the higher numbered terminal. From H1 to H2, and from x1 toward x2, etc. Try thinking about at how the coils look if they were laid out flat like the vectors. In other words, what if you took out the volt meter, and then flipped the x1-x2 coil out to the left so that the assembly was laying like an open book? The high side vector would point out to the right, and the low side vector would point out to the left, just like he drew them! Think about it. The reason you get 108 volts is because you have 120 volts to the right, and 12 volts pointing out to the left and subtracting from the 120 volts! In other words, the vectors are in opposition! Does it make sense to think about it that way? Let me know. If it doesn't I can draw you some diagrams and email them to you.
ahaaa now I know !!! THAnk thee so much SIR !!
I'd have to agree with the rest. Sir you're a awesome professor. I'm currently taking electical/electronic engineering, and my professor doesn't seem to have enough time to present this information clearly. I'm so glad I came across your video. This help me out in more ways than I'm learning in person in class. Thanks for the nice pace, and fully explaining the breakdowns.
Wow not even half way through and way better understanding than any other videos. Great teacher! Some people can just teach very well
no sound
I spend an hour every morning studying your videos. I love this stuff! Great great videos!!
At first hisr talk made me giggle but... This is the best exposition "on tape" ever!
You have not mentioned why there is a phase shift of 30 electrical degree b/w the primary and secondary. What is the reason ?
+Bharath Krishnan start watching the video again at about time 3:20. Dennis mentions a 30 degree phase displacement several times. Then he goes on to discuss the alternate displacement of 210 degrees.
Good video. Really clicked it for me too. Three phase that is. This guy is a good teacher. some people just have a knack for making you understand.
You should very short explanation on every definition that you say other wise you will never attract a young audience.
Young audience here. Not looking for entertainment. Looking for explanation. He does an amazing job doing that, I appreciate him not simplifying it. This video rocks
It is wonderful to hear the voice of my old Coach, Dennis, Keep the lights on in Heaven.
+Greg Burrell thanks for the kind comments. I miss Dennis every day!
+merchantjts Dennis came to Sioux Valley Energy to teach some of us from SVE and also some from Brookings, this was at the time when he was developing his own criteria, so we were taught both from the IBEW and his own. Now I live in Grand Junction Colorado and just started as an instructor at the Western Colorado Community College - Electrical Lineworker Program. GB
This is the very useful programme. Thank you.
this is good
This really helped me quite a bit! I was struggling to understand it, and then you drew it in a very understandable fashion. Thank you for this help!
Thank you for taking the time to post these videos. Very helpful. I'm an electrician / jointer by trade, we never learned anything like this back when I was studying
