The slot effect refers to the increase in inductance of a conductor when it is placed in a slot or groove. The formula to calculate the slot effect inductance depends on various factors such as the dimensions of the slot, the material properties, and the frequency of the current passing through it. However, a simplified formula for the slot effect inductance is:
Where:
- is a coefficient depending on the geometry of the slot and the shape of the conductor.
- is the diameter of the conductor.
- ℎ is the depth of the slot.
- is the width of the slot.
