Expert Answer

Examination of the problem.

We are authorized to answer one question at a time since you have not mentioned which question you are looking for, so we are answering the first one, please repost your other question separately if you want to get answered.

 

In the given problem the supply is star connected and the load is also star connected. The R.M.S value of the supply voltage is given also the load is inductive in nature. The approach,  to solve this problem will be to first draw the sketch of the supply end after that we will draw the load end sketch. After that, both will be combined together.

 

Supply end

Three-phase Y at the supply end. The phase difference among each phase will be 120degrees and the value of the R.M.S voltage is given.

 

The phase voltages are as follows:

Load end

The loads are purely inductive therefore the voltage will have the leading phase of 90 degrees as compared to current in the star-connected load winding.
