excellent explanation brother.. i felt very happy and knowledgeable after seeing this video.. would request you to upload such ETAP content with such an in depth explanation. Thanking you brother..
This is so lit, I like this video so much, so informative, In more than 30 minutes, I've learn the basic in ETAP, hopefully you've create more videos about this software. Thank you from Philippines
Sure brother, but it will take some time, there are videos in solar energy which are scheduled on RU-vid as I currently working on my master so I am pretty busy, but I promise to make it in the future.
The cable is 4(4CX500+240)mm2, not 1C. You have choosed 1C, 0.7Kv, 500mm2, you should go to other choice for 4C not 1C. The arrangement of the cables from the single line diagram says FOUR CABLES each cable is 4C (FOUR CORE), not each is 1C. Your choice is right if it is 4(1CX500+240)mm2. Thank you for your effort.
Hi Hassan, You didn't notice that there is another option called number of conductors per phase, you will see that it is written as 4 conductors per phase which provides for each phase a 4 conductors and our system is a three phase, so you will have the required number of conductors.
@@KhadijaAcademy so basically to solve voltage drop is changing tap rate on transformer by decreasing the primary and adding capacitor. what i need to know is why did you set the capacitor bank into 200 kvar, why ?
Nice presentation. However one question here. Why the cable model is not having the capacitance ? Cables have a non negligible value of capacaitance that has to be taken into account
Hello.. I'm really interested about your video series. Wonderfully explained. However can you kindly explain the applications of 2C, 3C & 4C cable in the library? (one example will enough) (I have seen in the comment section questions about using 1C cable and I understand that it because of this is a single line diagram and we are considering only one phase) Thank you very much for your effort!
Hey, Thank you for your nice feedback. I appreciate it. Let me explain this as many people are confused regarding 1/C, 2/C and these things. First, what does 1/C mean? 1/C means that the cable has only 1 core, which means, if you have a three phase system, you will need 3 of 1/C cables to provide three phase power. If you enable the display of how many cables utilized in the display options of the load flow, specifically, in the tab "AC" and tick on "size" beside the cable. ETAP will show you how many cables are required based on your selection. 3/C means that the cable has three cores, which means, in a three phase system, you will need only one of it to supply three phase power. In ETAP, if you selected the first option, you will find a number of cables written as 3-1/C which means that ETAP selected 3 of this single core cable to supply electrical power. However, if you selected 3/C, you will find it selected only one, as it is enough for the system. 2/C means 2 cores in one cable, 4/C means 4 cores, and so on. The neutral is not shown in the main library from what I remember. If I remember correctly, the neutral is added separately from the tab "Configuration" in the cable settings, then selecting the neutral from the auxiliary library with the size needed.
I just checked out on ETAP, if you choose 4/C, then you can have three cores for the three phase system and the fourth one can be neutral or protective earth. This can be set from the "Configuration" menu in the cable itself by selecting the neutral as main cable.
excellent video, can u please explain about number of conductors option while selecting cable from library? As you used 1Core Cables for all loads and similarly 1 Core Cable from the transformer?
Hi boss, it seems, it has mistake in selection of cable, instead of selecting 4 core cable you are always selecting single core cable from the beginning.
Thank you Malik, i haven't tried opening new version files in older Etap but if i didn't work, i think you have to do all the calculations and information addition again to the program.
Sir, its Incredible , but i want to that can i import the data from Autocad to E Tap ,,, Suppose I am interested to Import the SLD from CAD to ETap ,How can i do that.......?????? Thanks, Noor(EDE)
Hi Noor, On File menu use Data Exchange, however you can not direct import the ACAD file. You need to change the ACAD file to XML file and then you can import that SLD in the XML format. There is a help tool on this, press F1 for more details.
Thx, I have one problem, when I select a cable of 3cx300sqmm and run the short circuit analysis and error comes up (the zero sequence is =0), even for cables like 185sqmm or 500sqmm, how we can solve this?
Khadija Academy Thank you so so so much!! It's a big help for my thesis this year. I wanna learn also about the concept of MVAR CONTROL - VOLTAGE CONTROL in etap thank you.
@@SANGAMEWORLD if it is available i will take 3 core, the problem is 500 mm2 is a large cross section area , so if you want it as a 3 core then it will be very costly and it will be very bulky and difficult to install , in case of lower cross section areas we can use single core, it is of course preferred to use three core but in some cases we are forced to have single core.
Well, it wouldn't affect the short circuit or the voltage drop analysis, we already selected the components in the single-line diagram of Autocad, this was a part of the electrical design course.

They are in the diagram, you can see each line contain a switch and beside it a number which representing number of amperes, this is our circuit breaker.
Hi Yasmin, I looked back to the video just to catch where i said "set" but i did not find it :'D, 4(4*500) means 4 conductors of R and 4 conductors of S and 4 conductors of T, each of 500 mm^2 and 4 conductors of neutral, hope it is clear now :'D
@@KhadijaAcademy for the 1000kva transformer the secondary current will be 1520Amp in this case we use 4x(4x500+1x240)the first four we call it sets number its like 4 cable of 4*500 on parallel to share the load because one cable of 4*500 mm not suitable to carry the load i wish its clear
