EMISSION OF EMG FIELDS OF EXTREMELY LOW FREQUENCIES DUE TO HV LINES OF VARIOUS TYPES AND THE CURRENT ENERGY LEGISLATION IN CZECHIA AND SLOVAKIA

Eleonora Čermáková

   The article deals with experiments designed to determine emissions of electromagnetic fields of extremely low frequencies 50 Hz (ELF EMF) from HV lines of 22 kV constituted by bare lines (classic bare conductors), insulated lines (conductors with basic surface insulation), shielded lines (electrically shielded conductors) and underground lines (electrically shielded underground conductors). The ELF EMF emission is discussed in terms of protection zones established by the amended energy Czech law 458/2000 Sb. and the amended energy Slovak laws 70/1998 Z.z. and 656/2004 Z.z. in connection with the current Czech and Slovak laws on the protection of health against non-ionizing radiation 480/2000 Sb., and 271/2004 Z.z.

Keywords: legislation, measurements, extremely low frequency of electromagnetic fields, high-voltage lines, (HV lines), HV distribution conductors with basic insulation, HV distribution shielded conductors, HV distribution underground shielded conductors
