A transformer is said to be under "no-load" conditions when nothing is connected to its secondary winding and its loading is zero. When under no-load, the transformer's secondary side winding is open circuited. A transformer is operating under a load when something is attached to its secondary winding, causing current to flow through the secondary winding. The transformer's performance under both no-load and load conditions is examined through phasor diagrams and by considering the effects of winding resistance and magnetic leakage.
