thanks everyone for prompt reply and explanation!

Another thing .. voltage drop in the neutral conductor stands too? as mentioned by bacon4life .. it would be 4.9*2 = 9.8V?

wow, thanks very much .. very informative!

Never heard of this but would be glad to get some explanation as well ...

Oops, Burnt2x .. i mean i have to supply the shed with 1 phase power supply only (230 V : PHASE-NEUTRAL) .. If you have more questions, write it , perhaps i am missing something

Ah yes thx :P They are tungsten lights at the far end and the 70 mm2 cable is Aluminium .. Mistake: 415 V instead of 415kV in original post ..ack Phew .. just started working as an engineer :| Takes a lot of focus Thx for the support! cheers

Hi Could you please correct me if i am wrong? I have this situation: To supply a shed 1.3 km away from a distribution transformer (22 kV/415V - three phase)on 230V, load = 1kW. 415 kV cable used = 70 mm2 - three phase. V/A/km of 70 mm2 cable = 0.87. Volt drop up to shed = 0.87 x 1.3 km x 4.4 A...

Thanks! i'll check it out :)

Hi I would like to know the clearance distance (vertical and horizontal) to be kept from 66 kV pylons (metal lattice towers) to buildings please? Thx
