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.
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 ??

Hi sir,fantastic explanation,kindly make video for current carrying capacity of particular armoured cables size(without knowing power) ,like 4 core 240 sqmm armoured cable.
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
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
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.
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..
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?

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
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.
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 apne resistance, reactance ka value galt le liya he . Apne Resistance liya he 0.6 jabki multi core aluminum cable ka Resistance he 0.568 ohm he . Reactance apne 0.1ohm liya he jabki aluminum multi core cable ka Reactance 0.07 he. Please explain if I am wrong
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

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..
K ratings are given in evry company's Wire catelogue. You can find K rating as per your need
You can get this from manufacturer or for normal calculation I will share the link in the description
Where can I find K factor tables? and why sin(fi) 0.6?
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?
Why you taken current as 139 while calculating voltage drop ???
Correction : for voltage drop
It is( 1.732*I*R*L*100) / V3ph * NO.of Run * 1000
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 ?
Would the calculation be the same for the cable from Inverter to the LT panel?
But sir i have 1 confusion is this for almunium cabels or for copper
Good 😊❤
Thank you 🙏🏻
Great❤❤

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

How derating factor to be devided instead of multiplying..can you clarify..
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.
