Oil immersed transformer is a common power transformer

The no-load current percentage of the oil-immersed transformer is 0.80%. No-load current refers to the magnitude of the primary current when the transformer is open-circuited on the secondary side and only the primary voltage is connected. The no-load current of 0.80% indicates that the transformer has a lower current loss under no-load conditions, which helps to improve the efficiency of the transformer and reduce energy consumption.

The no-load loss is 0.065 watts. The no-load loss mainly includes iron loss and stray loss. The no-load loss of 0.065 watts indicates that the energy loss of the transformer under no-load conditions is very small, which further improves its operating efficiency and energy saving effect.

In terms of load loss, the parameters provided are 0.455 watts and 0.430 watts. Load loss refers to the loss caused by the coil resistance of the transformer under rated load. These two values ​​may correspond to different load conditions or different working environments, indicating that the loss of the transformer under load is also relatively low, reflecting the high efficiency performance of the transformer.

The impedance voltage is 4-5%. The impedance voltage refers to the percentage of the voltage applied to the primary side when the secondary side of the transformer is short-circuited at rated current. The impedance voltage of 4-5% indicates that the transformer has better voltage regulation capability under short-circuit conditions, which helps to protect the stability and safety of the power system.
