FEM simulation of three-phase busbars made as rectangular copper conductors 6 x 100 mm (spaced by 100 mm), carrying 50 Hz current - proximity effect significantly alters the current distribution. The effect is linear in the sense that it scales proportionally to the current amplitude (same shape of current density distribution, regardless the current amplitude).
The currents are set as:
- phase 1 (left) = 1 + i*0
- phase 2 (middle) = -0.5 + i * 0.866
- phase 3 (right) = -0.5 - i * 0.866
The results were generated with the software Finite Element Method Magnetics created by Dr David Meeker. |
