The effects of a fully-loaded transformer

As transformer have their load increase it makes sense that the current would increase as well.  What is sometimes forgotten is that when current increases in the secondary it also increases in the primary.  This is where things can get tricky.

As current increases in the primary so will the volt drop across the lines running to the transformers windings.  This can cause an issue in that by the time the voltage is at the winding it will be smaller than originally anticipated.  

A decrease in the primary voltage also means a decrease in the secondary voltage.  To really dig into what I’m talking about make sure that you watch the video above.
