Totalnoloadström
Totalnoloadström, also known as no-load current or no-load loss, refers to the current that flows through an electrical transformer or inductor when it is not carrying any load. This current is primarily due to the magnetizing current required to establish the magnetic field in the core of the transformer or inductor. The no-load current is typically a small fraction of the full-load current and is composed of two main components: the core loss current and the magnetizing current.
The core loss current is responsible for the hysteresis and eddy current losses in the transformer core,
In practical applications, minimizing no-load current is important for energy efficiency, as it represents a constant
To reduce no-load current, designers may use materials with lower hysteresis and eddy current losses, such as
