Sir, usually for earth mat design we consider soil resistivity data at depth or spacing of 10meter for determining soil model. What should be the depth or spacing at which resistivity data should be considered please guide and also tell if there are any references in IEEE, for the same. Thanks

I’m sold on the high voltage system.

Hello, very nice but you missed something. The high voltage battery 560v consists of 10 x batteries in series and you compare the numbers with 1x51,2v battery. The correct comparison must be 10 in series or 10 in parallel and all numbers are equal! Also in parallel connection if 1 battery has a weak cell and falls behind in discharging the others take care of it whereas in series there is no help and the battery discharge equally so gets hot and stops the system. In parallel you can continue with 9..

Nice presentation but would hv been better if you had pictorial view of actual pv installation with lightning arresters, SPDs, earthing, etc.

where we can download the slides?

Earth resistance can be upgraded during time of Erection of substation or during mesh greed maintenence effectively using latest technology and material availability.

Hi. I need to calculate my home battery bank needs. In your video, How do you obtain the 5074.94 ah battery capacity to support the load for 10-hour operation on a low voltage battery of 51.2 at a power of 20.78 kw? Please to hear and show how this is derived. Thank you.

very good

Very helpful video

Very good.❤

Sir, Why is plant grounding not based on step and touch voltage calculations? Why just substations(IEEE-80)?

Really appreciate! Thanks heaps!

That was beyond useful. Thank you very much

Very good explanation sir..Are you the lecturer from Western Sydney University?

"promo sm" 😈

Very good explanation, sir can you tell me which book you follow?

Perfect job, really appreciated Dr. Dr. Nassereddin, would you please tell me if there is a difference between LV substation grounding and MV substation grounding?

👎

Awesome

👍

What Is the difference between grid resistance calculation shown in ieee 80 by sevarks formula and ieee 142 chapter 4 , Table 13.

👌

can I have the slides please thank you

Perfect representation bro. Got a question 1- if we have an MPPT wind / solar controller, where we have to connect the inverter for ac household equipment ? 2- If we have an MPPT solar/ wind hybrid controller Instead of connecting the +/ - DC to the battery, can we connect +/- DC to solar MPPT inverter and let the inverter charge the batteries ! Thanks bro.

Great presentation Doctor

Thank you for your sharing ! However, could you show the calculation by using software of two-layer soil model? IEEE 81, Annex A and B?

Hello Dr. Mohamad, you mentioned reading the book in the video - where can I download/buy this book please? Thanks

Hi doctor Can I have your email for consulting ?

you did not include the hybrid design with battery design

Huge Thank you from a UK friend. I've spend 2 weeks 6h a day researching about putting in an off grid system. And bam! The best video with how to buy the correct items and how to set it up too.

Split factor sample calculations required to understand further

Why yo don't speak en arabic

Thanks for the video sir...It will be highly beneficial if you kindly continue this session..👍

Could you share the material ? Thanks

Great video Dr, keep it rolling 💪🏼👏🏼

What happens to step potential and touch potential if system is with NER reducing the ground fault current?

Excellent presentation

Great explanation sir

Amazing

Really find your presentations informative and resourceful.

I am going to watch all of these videos! Thank you!!!

A great proposal for Lebanon. I hope the Lebanese government can look at this seriously.

Ok followed everything except for how you selected a/h value from the Sunde's chart. The first time it seemed to correspond with the calculated p2/p1 value, but the second time seems arbitrary. The only correlation I am able to find between the 2 examples is they both seem to be close to the middle of that section of the Sundes Curve.

good lecture. but poor sounds and appearance

can I have the slides please

Thank you for the nice lecture!

how about not using Overhead lines ie use under ground cables

well done, very helpful
