Answer / saadi

Can i connect Dyn11yn11 parallel with Dy11y11 – DeltaHV side Dual LV winding star connected? I have 7 dry transformers with Dyn11yn11 configuration but we didn’t connect neutral with the transformer. Now i am thinking to order a new oil transformer of Dy11y11 configuration. According to my understanding, there won’t be any problem because the difference is just having neutral connection out or not?

What is the meaning of electricity? How it is being produced? Can we store the electricity? When we produce electricity what is the capacity of voltage current we are getting? If we need 440 volts how to get it? In case, if we want lower than 440 volts how to change it? Please answer?
