Transmission Line Sizing

[BoyNaruto]

We are on the process of planning our new fabrication plant and the we need to have 6pcs. 500KVA transformers. The existing High tension on the area is 30,000V. I am not sure of how much is the capacity of the line in terms of Amperage. Upon calculation, each one of my 500KVA transformer would need 9.63A, multiplying to 6, then I would need, 57.78A,,,at least 70A of current capacity from the grid.

Anyone can help me find the exact Feeder size based on this 70A requirements? Do I already need an electrical substation in our case? The land area is almost 10Hectares an I am hesitant to run low voltage distribution in each building. Thanks

Any 30 kV overhead line will be capable of carrying 70 A. You need to discuss your power requirements with the electric utility serving this facility.
