transformer voltage ratio
(OP)
Hi,
There is any guideline from ieee or from your experience to set the maximum voltage ratio for a distribution transformer? I need to decide if install a 33 kV / 0.4 kV 2 MVA transformer or run a 4.16 kv cable from a 500 m away substation, and install a 4.16 kV / 0.4 kV 2 mva transformer.
Please advice,
Regards

RE: transformer voltage ratio
No experience with the cost of cabling for the 500m at the different voltages though so you would have to factor that into your decision making.

The definition of 'foreseeable future' would be the present value of the 4.16 kV installation plus the present value of the future event to replace it. If that event is far enough out, its PV approaches zero.

Actually the feeder in 33 kV is more costly than the 2 MVA transformer. Regards
