Electromagnetic disturbance emissions tests

RRT performs various measurements of radiation of electromagnetic emissions in the frequency range from 0 Hz to 18 GHz.

Electromagnetic disturbance emissions are tested all year in whether protected OATS and/or anechoic chamber at the distance of 3 m or 10 m.

Vehicles electromagnetic emission tests of the are performed in an open test site and the trains electromagnetic emissions measurements of the performed at an agreed location (under suitable environmental conditions).

RRT performs these electromagnetic disturbance emissions tests:

Enclosure port:

  • Radiated disturbance test in the frequency range from 30 MHz to 18 000 MHz;
  • Radiated magnetic field test in the frequency range from 9 kHz to 30 MHz.

 AC power port:

  • Conducted continuous disturbance test in the frequency range from 9 kHz to 30 MHz;
  • Conducted discontinuous disturbance test in the frequency range from 150 kHz to 30 MHz;
  • Conducted disturbance power test  in the frequency range from 30 MHz to 300 MHz;
  • Harmonic current emissions test  in the frequency range from 0 kHz to2 kHz;
  • Voltage changes, voltage fluctuations and flicker tests.

Wired network port and signal input/output port:

  • Conducted continuous disturbance test in the frequency range from 9 kHz to 30 MHz;
