👌

pleaee make part2 of HT side cable selection

salam which table is in bs7671 its similar to table 4h4a

please share the clause for point of supply for public and private as per NEC

seen

Can you give nec ref code for 11 kV cable size

You are speaking of 100kva , but displayed as 1000kva.I am confused

If the 25mmsq of cable arrivlved from table then why you moved to 240

HT SIDE YOU DISPLAYED IN DRAWING 100 KVA TRANSFORMER ,IS IT 1000 KVA OR 100 KVA ?

Why is power factor not considered?

Why we take 100kva transformer

sizing simplified

Wrong! there is no cable under 35 mm2 in HT line,3 core...

Cable sizing information is wrong. If u consider 1000 kva that's amp capacity is 52 amp Let's move further Include derating factor 0.65 This is value of soil resistivity , depth of laying and temp factor 52/0.65 = 87 amps Available size is 50 sqmm 3core xlpe / PVC swa/PVC 1000 kva trafo short circuit is 0.85 ka another hand 50 mm cable short circuit rating is 7.5 ka Hence it's proof 50 mm square z sufficient. For safer side u can go for 70 sqmm

voice is confusing voice 100kVA,written 1000kVA?

Ur info is not confirmed in this vd because u r concept not clear

False information
