QuoteHi I am a retired electricity teacher in Canada
I am used to street transformers using single phase HV input and a dual 120 volt center neutral output to homes.
Here in Mexico I see transformers on poles fed by 3 HV phases with 4 output connetors!!
Coulsd someone give me details on tha type of distribution?

OfflineThe incoming lines are MV 3-phase/3-wire and the outgoing lines are LV 3-phase + neutral/4-wire.
The transformer is a Dyn configuration
This system is commonly used in Europe and the rest of the world outside North America
