How are stars and triangles used in power distribution systems?
Thread Content
Dear sea friends, I hope to get everyone’s help. I have a question: I really don’t understand how stars and triangles are used in power distribution systems Especially, what connection method is generally used for the section from the transmission line to the customer’s transformer? Is there any impact? Thank you so much~!
In China, transformer connections for 6,10 KV customers are generally of the D type, while for other voltage levels the Y connection is used!
