There are 360 ??high-rise households in a community in Jiuquan, Gansu Province. The design requires a load of 6KW per household. How big a transformer is needed and how to calculate it?

Look at the specific distribution of each building in your community. Rough algorithm: 360 households × 6KW = 2160KW. What is the simultaneous rate coefficient allowed by the local power supply department? 360 households should generally be between 0.35-0.5. If 0.35 is 2160KW × 0.35 = 756KW, the transformer capacity must be around 900-1000kVA. As for the number of transformers, it can be one 1000kVA or 400 500, 315 630, 315 315 315, 500 500, etc. according to the distribution of each building in the community.
