Voltage drop calculation method for Distribution line (LV Cable) 

Sir your channel is beneficial for the students. Please make a video on Bill of Quantity. We follow your method and it works.

Great job you have done here sir, just a little observation. To calculate the current between T1 to T2, I feel that, it should have been (63.51*1000)/(1.732*(415-1.13)*0.85)=(63.51*1000)/(1.732*(413.87)*0.85)=104.44A and not 103.88A.(While considering the voltage drop) Now, going by the factor you used in calculating the current(I=1.64P) To calculate the current flow between two nodes while considering the voltage drop across the feeder, I feel that it should be: I=(1.64P)*(415)/(415-1.13) and not (I=(1.64P)*(415-1.13)/(415) as you did. This gives: I=(1.64P)*(415)/(415-1.13) =104.4A while I=(1.64P)*(415-1.13)/(415)=103.88A 104.44A should be the correct answer. In all, you did a great job and I have learnt a lot from your video. Thank you so very much!

Can you please show the calculations taking place inside the excel spreadsheet

amazing calculation to voltage drop I am sure this calculation will support us in electrical power filled thanks

PLS GIVE THE 1PH SOLUTION

hi sir very good i have a 1 problem what about 1 phase VD

Great Explanation! But it seems the values differs with EDR program. Total amperes matches with EDR. But Segment VD% and Cumulative VD % not matches with your calculation. I think the constant has some issues with it! Not sure what constant they are using. Is there any standard list for constant? Can you please check

easy and amazing calculations to vdrop, may you kindly share the excel sheet if possible.

Excellent

shall we get the same excel calculation for bus bars.

Very nice, can you share excel sheet

best video bro
