I have some questions about POWER TRANSFORMER These are my questions:

1.What do the problems occur if we paralleled TRANSFORMER with a heavy load???

2.Why do the magnetical and power losses of transformer depend on the frequency??

Thank you for your attention.......................

 

hi,

problems that you will encounter in a parallel configuration are as follows:
1. wrong connection of terminals (phasing)
2. voltage output difference of each transfo
3. current rating of each transfo

for your question #2, see the transformer topic.

 

Just to help you get around the forums:
