50hz no leakage pdf

For a practical transformer, if the secondary winding is kept open circuited, it is said to be in no-load condition. As the secondary current is zero, there is no magnetic leakage in the primary and a small current is drawn to supply to the iron losses. Thus, the no load input power is equal to the iron losses.
