Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world

This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. It describes the measurement method to verify the emissions, and gives the cartography values of the fields most frequently encountered. This European Standard specifies the emission limits of the whole railway system to the outside world. The emission parameters refer to the particular measuring points defined in Clause 5. These emissions should be assumed to exist at all points in the vertical planes which are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations. Also, the zones above and below the railway system may be affected by electromagnetic emissions and particular cases need to be considered individually. These specific provisions need to be used in conjunction with the general provisions in EN 50121-1. For existing railway lines, it is assumed that compliance with the emission requirements of EN 50121-3-1, EN 50121-3-2, EN 50121-4 and EN 50121 5 will ensure the compliance with the emission values given in this part. For newly build railway systems it is best practice to provide compliance to the emission limits given in this part of the standard (as defined in the EMC plan according to EN 50121-1).

Železniške naprave - Elektromagnetna združljivost - 2. del: Sevanje celotnega železniškega sistema v okolje

Ta evropski standard je namenjen opredelitvi elektromagnetnega okolja celotnega železniškega sistema, vključno z mestnim množičnim prevozom in lahkim železniškim sistemom. Opisuje merilno metodo za preverjanje sevanja in podaja kartografske vrednosti polj, ki se pojavljajo najpogosteje.
Ta evropski standard določa mejne vrednosti sevanja celotnega železniškega sistema v okolje.
Parametri sevanja se nanašajo na posebne merilne točke, opredeljene v točki 5. Za sevanje se šteje, da obstaja na vseh točkah v navpičnih ravninah, ki so 10 m od osi zunanjih elektrificiranih železniških tirov ali 10 m od ograje podpostaje.
Tudi na območja nad in pod železniškim sistemom lahko vpliva elektromagnetno sevanje, pri čemer je treba določene primere obravnavati posamično.
Te posebne določbe je treba uporabljati v povezavi s splošnimi določbami standarda EN 50121-1.
Pri obstoječih železniških progah se predpostavlja, da bo izpolnjevanje zahtev standardov EN 50121-3-1, EN 50121-3-2, EN 50121-4 in EN 50121 5 glede sevanja zagotovilo skladnost z vrednostmi sevanja, podanimi v tem delu.
Pri na novo zgrajenih železniških sistemih je najboljša praksa zagotoviti skladnost z mejnimi vrednostmi sevanja, podanimi v tem delu standarda (kot je opredeljeno v načrtu elektromagnetne združljivosti v skladu s standardom EN 50121-1).

The emission parameters refer to the particular measuring points defined in Clause 5. These
emissions should be assumed to exist at all points in the vertical planes which are 10 m from the

4 Emission limits
4.1 Emission from the open railway system during train operation
The emission limits in the frequency range 150 kHz to 1 GHz are given in Figure 1 and the
measurement method is defined in Clause 5.
Annex B gives guidance values for typical maximum field values at fundamental frequency of different
electrification systems which may occur. They depend on numerous geometrical and operational
parameters which may be obtained from the infrastructure manager.
It is not possible to undertake complete tests with quasi-peak detection due to the reasons stated in
Annex A.
There may be cases in which radio or other railway external services with working frequencies below
150 kHz are in operation close to the railway system. The EMC management plan covers these cases
and an adequate level of emission from the railway system on these working frequencies may be found
in the values given in informative Annex C hence no guarantee can be given for an undisturbed
operation.
4.2 Radio frequency emission from railway substations
Radio frequency noise emission from the railway substation to the outside environment measured
