Hi,
What does rated output in a transformer signify?
Is power same(or almost same) on both sides?
In short circuit test, we apply reduced voltage to HV winding so as to circulate rated current in HV. This will cause rated current to flow in LV. But as per definiton of rated current, rated current=(rated output/rated voltage). So how come rated current flow with reduced voltage?Is power maintained constant in this case? If power is maintained constant then what about open circuit test?
Somebody pls help me. I m terribly confused. I might sound stupid but I really want to clear this..
