  • Cable impedance - ePanorama

    First, you want to drive the cable with an electrical source that has an output impedance equal to the characteristic impedance of the cable, so that all of the source's output power goes into the cable, rather than being reflected from the cable's input end back into the source.

    In general, the cable impedance can be calculated in accordance with IEC 60909-2 'Short-circuit currents in three-phase a.c. systems - Part 2: data of electrical equipment for short-circuit current calculations. This standard give gives appropriate formulae for a variety of single and multi-core cables with or without metallic sheaths or shields.

It consists of a source (a power inverter), a three-phase power cable over a return plane (a metal chassis), and a load (a motor). The power inverter produces CM current on the power cable, which can generate unwanted radiation. A ferrite toroid can be placed on the power cable to reduce CM current.
