Transformer Testing Procedures
Transformer Testing Procedures
(OP)
I want to determine transformer efficiency. I have done an short circuit test to get the losses. Then I connected the transformer to a resistive load which was set to draw the full load rated current in the secondary. Using two wattmeters, I measured the primary watts and the secondary watts to determine efficiency. My problem is this - the difference between the wattmeters indicates the losses but this figure does not tie up with the losses I got when I performed the short circuit test. What am I doing wrong? Any help would be greatly appreciated.
