This is an old issue that we have answered several times in this forum, please look around. Long story short, the solution is as follows:

As you can see, you need to calculate the voltage bases for getting the right voltages in pu. Also, it doesn't make sense to connect a 35 kV load to the secondary of a transformer at 11.5kV rating. Their voltage ratings need to match. Please keep your models consistent.
