Radiation coupling
Electromagnetic fields travel through space with the velocity of light c = 2.998 x 108 m / s and may influence electrical installations in the near or far surroundings of the source. Typical sources of electromagnetic fields are radio or TV transmitters, mobile telephones or any other kind of wireless applications. The high frequency parts of fast signals or of fast transients (ESD, surge, burst lightning) may also lead to the radiation of electromagnetic fields by cables or any other conductive parts of the electrical installation and may cause disturbances in electrical systems in other parts of the building.
If the disturbances on the power supply or data network contain high frequency components, other elements of the installation may act as antennas and radiate the electromagnetic fields. The Hertz Dipole may serve as an elementary model to estimate the magnitude of radiated fields. All conductive parts of the electrical installation may serve as antennas, including
x cables
x openings and slots of cases, cubicles etc. x printed board strips.
