Great vedio sir, I have'nt seen this type of content on this particular topic in which any industry can actually calculate their cable size and will no longer be dependent on assumptions.

Hi, thank you for this video. I have a quick question for you, instead of using 95sqmm size cable, can we route two run of 70sqmm cable or not??? Please tell me the reason. Once again thank you.
Dear Raman ji this is for aluminium cable or copper cable ? For both these same formula will be applicable or different if different formula then please tell

Ok Thank you for detail video Kindly requesting to provide details for Multiple cables running in ground Multiple cables running in air through cable tray
this is very good but i have a small doubt let's consider the 80kw load is inductive so the starting current will be more don't we have to consider that in it ??
Hey bro! Did you got any reference book or standard? If yes can you share it to me and if you are experienced in this field can you tell I should go by this video?
One question I have is that for calculating full load current will the current be divided by k factor value or will it be multiplied by k factor value beacuse k factor is correction factor means it is derating the cable current depending on certain parameters so full load current should reduce and for that we should multiply the current by k factor. This is my assumption, please correct if I am wrong.
As depth of cable ur selecting from chart 1050 Meter and that sqmm of cable how can we decide that 70 sqmm. after correction factor calculation only we can decide sqmm of cable on wht basis or consideration we are taking 70 sqmm before calculating correction factor
Sir could you please help me our load ism1500kw so how many cables of 300mm aluminium would we need from transformer to load , cable length approximately 50m

Some industry is maintaining a power factor of 0.95 and if we are to choose wire size then we take solar load into consideration. e.g. if we have a 50 kw solar project then Solar load will be at a max not more than 50kw and power factor will be maintained. So can we chose the wire size on that basis or we will have to consider PF as 0.8 for all cases. Plz clear.
Right. My mistake. In star mode, phase current equals line current.But here we are calculating voltage drop making use of current. Is it still required to be multiplied by root three?
Thank you for the good information. I would like to know regarding the K ratings.. On which basis we should we take the K ratings.. I mean do we have any BIS Or ISI to prove.. If ask someone..
There are different type of gauge of wire available in market in same category like 2.5mm wire different companies has different gauge you don't even mention a single time about gauge i want some information about it how can i contact you
I can't understand value of jsinφ because you take R = 0.6 and sinφ=0.6 both reading value are same so I confused. which parameter value putting in the place of sinφ
@Solar Facts : Dear sir i think you mis calculated current in voltage drop equation. Value for current should be 142.28 Amp as per my thinking. Please correct me if i am wrong.
Sir 4 core cable me nutral current kitna flow karega or agr humara system pura sirf unbalance ho 3phase and nutral ko hum sirf single phase and nutral use karrahe ho to kya nutral wire 3 phase wire ka sum hoga
Can u please explain why u choose 70 sqmm directly and started selectin gparameters as per that , u didn't give any contex or explanation over there , 9.47 minutes
This was random selection just to check whether it is ok or not I will also share one video where you can find the calculation for the cross section of wire

Aoa dear your video is very helpful... Kindly give just one answer...
If I use the 4 core 70mmsq then it's means that number of cable run = 1...or 4
1 run 4 core
One question I have is that for calculating full load current will the current be divided by k factor value or will it be multiplied by k factor value beacuse k factor is correction factor means it is derating the cable current depending on certain parameters so full load current should reduce and for that we should multiply the current by k factor. This is my assumption, please correct if I am wrong.
Regarding voltage drop calculation Are you sure about considering current value 139.12 amps . Why not used current rating 142.28 ?
Let me check
As depth of cable ur selecting from chart 1050 Meter and that sqmm of cable how can we decide that 70 sqmm. after correction factor calculation only we can decide sqmm of cable on wht basis or consideration we are taking 70 sqmm before calculating correction factor
Would the calculation be the same for the cable from Inverter to the LT panel?
Sir could you please help me

Good work
Thank you
@solar Facts thanks a lot for this video. can u share the book name about k factors table u have used in this calculation???
K factors are given by manufacturing company. You can follow them
That you can get from the manufacturer whose cable you are going to use
Hi bro in last while calculation of voltage drop you write 139 amp but while adding "k" factor this is 142 so what is correct ?
Sir it great please made single phase wire size selection
Ok sure I will
For Home wiring we also find voltage drop?
Yes you can find the voltage drop for home also
Same method?

Sir, cable selection me short circuit current nahi consider karte hai kya ?
Karte hai
Will make a separate video
But sir i have 1 confusion is this for almunium cabels or for copper
Hello sir....generator voltage too low ... inverters main issue hai ..?
You have to keep the voltage In range of inverter
Good brother,.But to finalize cable, you must check the short circuit capacity of cable also...
yes
Where can I find K factor tables? and why sin(fi) 0.6?
i have a comments against your subject , final calculation which your apply instead of 1000 u r putting 100 , please clarified this , and over all v.good
That is 1000 there is written error

Voltage drop me system full load current lena tha ya nahi?
wher u apply value in formula there please clarified mean where divided the value u r put 415 x1 x100 instead of 1000
That is 1000 there is written error
Sir, Inverter always work on unity factor, so why you. Have consider .8 PF
Can you explain ?
Inverter power factor is unity but as per my consideration power factor always depends on load that why I have take 0.8
Excellent video
thanks
Lot of thanks.....
thanks
Why you taken current as 139 while calculating voltage drop ???
Can we use simple polycab 4sqmm ac wire in 3kw solar ongrid system?
Yes
But you have to check cable length

how did you select 70sqmm=164Amp

Very helpful videos sir
Thanks and welcome
100 kider sey aya?
From where did u get k value as .9
Why you consider current valve 139 intead of 142.12 amp ? I think there is some mistakes?
It is because the full.load current flow is 139 amp not 142amp.
Plz share the link of the Tables which you are used .

generally we consider power factor 0.80 for the wire calculation
K6 ka value aapne consider ni kiya hai. What about that?
By default it is 1
Good endeavor. But, to calculate voltage drop, why current be multiplied by root three? In star mode, phase voltage equals line voltage.
No
Sir in delta phase voltage is equal to line voltage
Right. My mistake. In star mode, phase current equals line current.But here we are calculating voltage drop making use of current. Is it still required to be multiplied by root three?
Great vedio sir. How can we put values of k factor like air temp.
There is a sheet from where you can find out the values of K

Thank you for the good information. I would like to know regarding the K ratings.. On which basis we should we take the K ratings.. I mean do we have any BIS Or ISI to prove.. If ask someone..

You took sin& =0.6 Can you pls explain how
We know cos @ = 0.8 from here you can get @ value then you can calculate sin @
