This article attempted to identify opportunities for smart meter enabled appliance throttling to avoid overloads in the transformer network. The focus was on the last transformer before a home, and I was surprised to read that 3-7 homes are on a 25 kVA transformer. Presuming I am not too far off in calling that a 25 kW maximum load, I'm surprised that transformers are not blowing up left and right. Five AC units across say a five home network pulling at the same time would do it ;-) Let alone a Tesla added to the mix. How is this resolved, or do I understand the entire issue wrong ?
