No-Load and Full-Load Losses (continued) Full-Load Losses
Typical Utility Load Profile •
Load losses occur anytime the transformer is supplying current to a load. Load losses for a transformer are generally expressed as full load losses. These losses include winding (I²R) losses and stray losses which increases with load and temperature. Stray Load Losses - caused by leakage flux inducing currents in structural components; influenced by geometry, shielding, magnetic design and manufacturing practices. Total losses = No load losses plus load losses. Application Load Profile determine the per day loss.
