2381i have been tasked with a design of protection, metering and control(PMC) relay panel extension to accommodate all PMC relays.There is an already existing panel where this one will be built.What are the design aspects for this kind of project? thank you.
2121we use Dyn11 trafo for distribution purpose, if it`s possible for replacing Dyn1. if it`s change means what will happen?
1 5062what is the difference between delta delta and star delta connection transformer? why we use delta delta transformer since it need earthing transformer for grounding?
2091two transformers of the same type, using the same grade of iron and conducting material, are designed to work at same flux and current densities, but the linear dimension of one are two times of the other in all respects. The ration of kVA of the two transformer closely equal to................? options: 16, 8, 4, 2
