In the case of cables on magnetic metal such as galvanised steel tray: ➝ The alternating currents in the cables produce changing magnetic fields. ➝ The eddy currents in the tray generate. Metal trays also have electromagnetic effects that impact cable ampacities including increased cable conductor resistance caused by the flow of induced current in the metal tray and heat-generating eddy currents. In. Abstract – This paper includes the results of the electromagnetic finite element analysis with regard to overheating problem of the power cable tray due to asymmetric magnetic flux density. This phenomenon was experienced in the utility power plant, Korea. Individual TnB fittings are used for each phase and neutral. 20 violation, induced. In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.
