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👍

Hello, , Mr Joe, it's very interesting calculation it makes me to understand more about star connection and delta connection into relationship.❤

Current EE student here, studying for my final at 5:00 in the morning! Thank you for these videos they’re great, I wish I found them sooner!

[edwardmungai]

Been hell reading through the books and I couldn’t understand this. You really saved me sir . We are always watching your videos for better understanding here in Kenya. Thanks champ 🙌🏽🙏

[emirjais]

reading books is not enough with out this kind of videos. Thanks hope i can successfully pass to my license examination on Electrical engineering. This video helped me digest every single doubts in my mind.

Dude THANK YOU VERY MUCH, truly. I have had 3 phase systems in my lectures for like 3 years and only now have I finally completely and confidently Understood them. THANK YOU SO VERY MUCH : )

[engineeringmaniac]

Thank you for making things easy for us to understand. I am a Civil Engineer and people like you made me love Electrical more than Civil.

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 Youtube, 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.

[PunmasterSTP]

Star and delta? More like "Superb and delightful!" Thank you so much for making such high-quality lectures and sharing them on YouTube.

[alialin]

thank you joe, currently in process of finishing off level 2 at college, worked on fire alarms and security systems for the past 12 years but obviously gone to college to electrical and been surprised with how much there is to take in and remember, your videos really are helping a lot

[sorinpetre]

Va mulțumim pentru video si explicații ati fost foarte clar si concis, cu adevărat un adevărat profesionist ❤👍, ati simplificat atat de mult si clar chiar pe aceiași planșa comparandule, pentru a fi mult mai UȘOR DE COMPARAT, eu nu cunosc bine liba engleza, dar plansa si modul de prezentare si scriere cu MARCARE DE DIFERITE CULORI TE AJUTĂ SA LE EVIDENȚIEZI MULT MAI UȘOR, , decat daca ar fi fost scris cu aveiadi culoare, meritați tot respectul celor care vau urmatit, am sa ma abonez si eu la dumneavoastră, va mulțumim

[augustineshako]

Your way of teaching is amazing, Been struggling with this for months, but i learned from your previous videos and answered these with ease

[davidkargbo]

Hi Joe I’m blessed to have you for my first time. You’re very good, I’m really blessed to have on line, thank you.

[tavongamundanga]

You are the best man. Believe me your explanation are so clear. I have been looking for something like this 😃

[vincentmasanja]

How are you Mr.Joe?Today I would like to express my gratitude to you for the training you provide. It increases the understanding of electricity. May God bless you.🙏

[matthewellis]

Star connected load? …is that ‘Y’ ? Holy moly, I’ll have to study this one again. Much respect to you for teaching this

[narayanguragain]

Thanks Joe, you literally saved me from a disaster.

[FelixAkuoko]

AMAZING! You've made this so simple to understand and put into practice! Thanks so much for boosting my confidence.

[nadeem]

Your videos are great Joe, love watching them and I learn so much from you.

I am regularly asked by young apprentices about three phase systems and star and delta configurations. This presentation is a great example to follow, with easy to follow calculations.
