Dennis Merchant on ferro-resonance in distribution transformers. This video goes with the power use and basic electricity portion of the Merchant Job Training & Safety Program.
Since I have not heard from you, a quick comment. You are thinking about a 3-phase wye connected load with a solidly grounded neutral. Of course you can use a per phase analysis in that case. Here we are talking about a transformer. A good discussion of transformer connections for an engineer is in chapter 4 of "Electric Power Distribution Equipment and Systems" by T.A. Short. By the way, nice hearing from you. I graduated from Michigan Tech in Power. Dr. Wiitanen was a great guy!!!
Hello i enjoyed the ferroresonance explanation how ever i was curious regarding the self regulating comment you made regarding grounded system . I was off the opinion when you solidly ground the neutral all the 3 phases operate kindaa independent of each other ..could u clear this query or direct me to some material i can read to grasp this better
Raksmey, I'm sorry you are having trouble with the sound. I just played the video on my computer and it comes through loud and clear. Have you checked the volume control on your computer? Also there is a volume control on the player window. If you continue to have problems, please let us know so we can get to the bottom of it.
Salil, thanks for the comment & question. I am limited in the way I can respond in comments. Please send me an email to merchantjobtrainingandsafety@gmail.com and I will do my best. It helps to draw pictures, I can send PDFs by email.
