Can anybody teach me how to draw the equivalent circuit for this diagram ?

I take it you are taking Power System Analysis! Do you have any other parameters for the electrical loads shown on the drawing you provided?
Without any other information, I can only advice you to apply thevenin's theorem to find an equivalent electrical circuit for it.

 

this is the partial solution but I dont think it is correct. Can any of you please guide me how to solve this problem ? What I want to find is the fault occur at each relay 1,2,3,4,5,6,7,8. Given the load is 5MVA

Very much appreciate
