Cable Size Calculation for Medium Voltage or 11kV Electrical Systems

[olalekanmagbade]

Thanks for making this video. It's the best I have found on this topic. Can you please provide info on how the reference materials used on this video? The derating factors and cable size tables will be especially helpful.

Thanks for sharing these valuable details.

Kindly send the link to get this chart.

de rating factor reduces the current carrying ability of the cable, so 187A x 0.76 = 142A, as the FLA of transformer = 131A, selection of the cable size of 50sq.mm is good. correct me if iam wrong.

Do you know about any software for a medium voltage cabling calculations?

[juanlotta]

It would be helpeful if you share the standards you're taking into account

[charinath]

what is the difference between HV and LV cable sizing?

[sniperchanel]

Thanks for share verry interesting content

How to calculate if we want to use 2 or 3 nos of cables per phase?

[sumedhaweb]

how can u add Rcos@ and X sine@ .these are complex numbers. it should be

[faisalbukhari]

Very Good. Keep it up. Make more videos.

hi sir, i gave one doubt if the length is 15000 MTR as my able length is 15KM shall i need to divide it my 1000 or 10000..

Hello! May I ask the references for the derating factors Tnx

[ScholarshipTamil]

Could possible to share supporting documents

[saeedahmed]

can you please share the excel sheet for the easy calculation for pakistan.

How many transformers can feed from m v switchgear in one loop

[zubairali]

from where you get the cos@ & Sin@ value? respectively 0.8 &0.6 please clear.

[thrinadnadh]

Hello Sir, what are you showing the tables to calculate HV/MV Cables from which IEC Code?

[tuleanhvt]

Hi H N, As I have known for the motors, we should be aware of voltage drop in both steady state & starting of motor. Could you explain for these cases of Motors?

[foras]

Could you please advise how we can find the Max. Load Allowed on 1 Feeder @ HT = 5MW or 6.25MVA or 328A?
