How much is the transformer loss in general?

The copper loss in the transformer is generally 0.5%, and the iron loss is generally 5-7%. The transformer loss refers to the sum of the no-load loss Po, the short-circuit loss Pk and the stray loss Ps. The transformer uses the principle of electromagnetic induction to A device for changing the AC voltage. Copper loss is the power consumed by the resistance of the primary and secondary windings when the current passes through the primary and secondary windings of the transformer. The copper loss is also called variable loss. As long as the current of the primary and secondary windings is kept unchanged, the measured copper loss That is the constant loss. The copper loss meter is used to measure the loss of the copper coil of the transformer, which changes with the load current, and the copper loss power is proportional to the square of the load current.
