What’s An Open Corner? - WHY is it Important? 🤔

Have you ever seen a transformer bank explode as soon as it is energized? In this video lesson we explore the importance of building and Open Corer on your Closed Delta banks. We talk about what it is, and how to use it to ensure that our transformer bank has no problems that could cause a fault.

One of the best descriptions of phase angles and connecting xfmrs Ive ever seen

I’m just now learning this trade and your videos already make since to me! Need a couple hundred more please 😂

[@billyr9840]

I love watching and learning from your videos. Im not in the field but but i was always extremely interested in your type of work since a very young age. The way you explain how these setups work is extremely easily understood. Hope to see more videos in the future. Thanks !

Thanks for this video.

Thank you for teaching me high voltage and understanding it better.

[@AlistairBostrom]

Your videos are wonderful. Take a bow for a job well done!

Nice video! First time vectors made sense to me!

[@TechOne7671]

A well presented video with good explanations and example.

Thanks Cory.

This is awesome information! I am very interested in learning more about transformers. You make this subject very clear. Thanks for sharing your knowledge with us. We need more people like you in the industry.

Great video an explanation. Even a beginner can follow this demonstration! When will you be making more videos? Just came across your channel.

nice and easy😀

Using distance was an easy way for my to visualize voltages between windings. In my neck of the woods 120/240V 3ø 4w delta systems are rare and where found are in old commercial and industrial buildings because in most cases a 120/208Y system is more appropriate. However I do see open delta 120/240V 3ø fairly often in rual areas, mostly on farms where the customer needs 120/240 1ø but also needs the ability to run light 3ø loads, such as a milker, augers/conveyers with motors of 7.5 HP or larger for example. I can spot these while driving down a country road by noting 2 transformers, a large and small pot,

I love all your videos, I love how thorough you are but explain it easily so everyone can understand. Was wondering if there maybe a workbook or downloadable files on some of the problems you go through in the near future?

[@Smile-hp1xg]

Great video for sure learned something but we’re your case grounds lol

[@Bone_Apple_Tea]

Looking for more info or a video, if you could, on parallelling two different polarity banks. Any information would help out greatly! Thank you!
