Hiya Joe, I qualified 21 years ago and Ive found myself glued your series of videos. I can always remember my eyes glazing over in college all those years ago, on some ac theory lessons including this! You are so good at explaining and making what was once a seemingly difficult topic, easy! If only you were my tutor back then!!! I think the beauty of these videos is you can pause and rewind until it sinks in, pausing and rewinding is difficult when your sat in a classroom! Keep up the good work Joe👍

@JoeRobinsonTraining 4 года назад

Wow, what a great comment. Thanks so much I love knowing that people benefit from my videos even if they're already qualified. Thanks again and stay tuned for more!

Thank you Joe. With Covid-19 closing college, online teaching isn't going well. I've just completed the 3-phase Star & Delta principles section of my level 3 C&G book as best as I could, not understanding it. Having just gone through your videos on Star & Delta tutorial videos on RU-vid, I have now gone back over this section, answered the calculations and my understanding is much clearer now than it was before I started. Thanks again.

@brandonfrancis8696 Год назад

Nice and informative video. I just want to add something. Since you are showing a three phase system which is connected in wye (star) and delta that means you are dealing with AC system. When you are dealing with an AC system try to avoid using the “R” (resistance) as loads, use “Z” (impedance) instead. The reason is: in an AC system, resistance is part of impedance. Impedance has two componnents-resistance and reactance. I hope you don’t get offended as you intend this for the beginners. Thanks.

my thanks to you, please clarify this, since the current is low in star connection, and more in delta connection, then why the motors are preferred to run in delta connection, using star delta starters.
