Loving the content finally something I can grasp .
Best professor that I’ve ever had at nova! I miss you!
Great info. UPS already has build in AC to DC converter, rectifier. That is how UPS is able to charge DC batteries. UPS also has a build in DC to AC converter, inverter. Thats is how UPS is feeding AC loads when utility power is lost.
Looking into a hob for a data center tech. This vid helped out a lot.
Many thanks for video
Thanks for your very useful information about Power Distribution for Data Centres and UPS
I've got a final exam in a few days and this is the only video that has helped me understand this, not even my lecturers made sense! Thank you so much!
Well explained
How about a inverter and rectifier
I already did a video for a full-bridge rectifier. And, the inverter is simply a DC to AC converter with a pulsing DC signal generator. The full derivation will require an extensive knowledge of integrated circuits. Does this answer your question?
So good 👍
remote power panel, does anyone know what that is? please it's really important
RPP are downstream from the ups. They step down from 480 to 208 or less. Feeding customer loads. That’ll be what the customer 20,30 amp 208v circuits are fed from
Begining your sentences with "clearly" doesnt fix a poorly worded explanation. It just tells everyone that didnt understand that they are dumb.
Image not clear
Close... But not quite. One line doesn't look like that at all, actually, but its a useful explanation for lay people. I build data centers.
True. It’s kind of close
2:55 to 4:26 needs correction. An Automatic Transfer Switch (ATS) selects between 2 or more power sources (example, utility power and generator). An ATS does not convert AC to DC. Based on your example, the UPS will receive 480V AC, convert it internally to DC to charge the battery, convert back to 480V AC....
This video is really designed for Data Center interviews. However, you make some good points. So I will review your comments and update the video.
wonderful, I am executing a data center and I found this video as easy, authentic and effective.
Could you do examples applying this knowledge?
Your videos are very helpful. Ty
Can you do a video on specific SLD symbols and diagrams?
every data center has two main power sources the pirmary one is Utility and secondry one is generator, so power comes from the main utility to the transformer then to MCb or main circut braker, then to MSB or main switch board then goes to main Utiltiy circut- then to ATS and from ATS it goes to rectifier this where the power change from AC to dc and then to invertor to change from dc to ac and then it goes to PDU and from there it goes via bus lines to the client computer or server racks ..
Why would the generator not be wired for fail over of the mains primary? That doesn't make sense to me to have the secondary power just be a generator. I could see if secondary was from a utilities provider and you had your generator on that circuit in case your secondary also went down maybe
The PDU in the rack is supply by a A&B Power Panel, each power panel has it’s own UPS back up,and all is backed up by your generator,most buildings have 2 generators
@@JustSomeGuy009 It does in reality. The mains output and the Generator power ouput connects to the Automatic Transfer Switch (ATS) or sometimes Auto Mains Failover (AMF) system. It’s the ATS that does the switching between Mains and Gen and viceversa. What you will typically have is The ATS is fed by output of: 1. Interconnections of Mains Feeder + RMU + Transformer + LV switchgear 2. Diesel Generator (s)
Hi Bisma's PROFESSOR
Love it
Nice video. Can you tell me the name of the mechanical pencil that you are using? Thanks.
Pentel Graphgear 1000 7mm
The video is gold, but I wish it was zoomed at the paper to see things clearly maybe a thicker pin : ). Thanks
??????? ?
You have Rs=R1+Rp & we established Rp was 2.5 ohms. why did we do Rs=10+5 instead of Rs=10+2.5?
Probably a typo. Can you send me the exact time in question?
This UA-cam channel is GOATED
where did you get 5 ohms for Rp?
wouldn't the highest number you get with 3 bits be 7? 4+2+1=7???
Yup. I have to correct the error. Thank you.
Great Video !
THANK YOU SO MUCH!
Please let me know how I can improve this video and other videos. I designed this channel to help people solve engineering problems.
