Yes!!!!
a transformer consumes a certain amount of power without load**. This is because when a transformer is in operation, eddy currents are created in the transformer due to the molecules in the air being excited by an electromagnetic field. These eddy currents generate a magnetic field to the core, which in turn generates a voltage. As a result, even if the transformer is not loaded, some eddy current losses and iron losses are generated, resulting in the presence of reactive power as well as a small amount of active power dissipation when the transformer is not loaded.
This power dissipation at no load is often referred to as no-load losses and consists mainly of magnetic flux losses and copper losses from the current in the windings. The iron loss is due to the magnetization loss produced by the iron core under the action of the alternating magnetic field, while the copper loss is due to the current in the winding to produce resistance loss in the coil. For dry-type transformer, no-load loss is fixed, with the load size has nothing to do, but long-term operation will cause energy waste and economic loss, so should reduce the no-load loss as far as possible.
