[Analysis Case] Proximity Effect of Cable Strands (Magnetic Field Analysis)
The input voltage is adjusted to use a voltage that results in a maximum absolute value of the current density of 1!
This is a case study that confirms the current distribution observed when an alternating current flows through a conductor bundled with 19 strands of wire, using magnetic field analysis. Since frequency response magnetic field analysis is appropriate, the software "PHOTO-EDDYjω" was selected. The input voltage was adjusted to ensure that the maximum value of the resulting current density (absolute value) is 1. As a result, at a frequency of 1×10^5 [Hz], the current density was almost constant, while at a frequency of 1×10^7 [Hz], a concentration of current density was observed on the surface of the outermost layer of the conductor. 【Case Summary】 ■ Software Used: PHOTO-EDDYjω ■ Analysis Results - 1×10^5 [Hz]: Almost constant - 1×10^6 [Hz]: Gradual distribution of current density observed - 1×10^7 [Hz]: Concentration of current density observed on the surface of the outermost layer of the conductor *For more details, please refer to the related links or feel free to contact us.
