Locomotive & Railway EMC Testing

Train and Railway EMC testing, compliance and approvals. The EN 50121-x sets out a framework for managing EMC for railways. EN 50121-x series also specifies the limits of emissions and levels of immunity testing. These requirements are applicable to each component and the railway system as a whole. Including within the boundaries of the railway itself and also to the outside world. This is to try to ensure that the when integration of new systems occurs that they are ‘fit for purpose’. In addition to complying with the appropriate EMC directive.

Including within the boundaries of the railway itself and also to the outside world. This is to try to ensure that the when integration of new systems occurs that they are ‘fit for purpose’. In addition to complying with the appropriate EMC directive.

The railway standards include both emissions and immunity testing. Some of the emissions testings include the basic Radiated emissions (electric field). This can be performed on a test site or at a location. Also conducted emissions on the traction AC ports, traction DC ports, Auxiliary a.c. or d.c. power ports, Battery referenced ports, Process measurement and control ports.

The immunity testing usually consists of relatively higher applied stress test levels. When comparing to consumer product testing. This is due to the harsh intended electromagnetic and transient environment of the railway. Immunity testing includes testing such as:

  • Radio-frequency common mode
  • Electrical Fast Transients (EFT)
  • Surges
  • Radio-frequency electromagnetic field
  • Amplitude modulated, radio-frequency electromagnetic field
  • Radio-frequency electromagnetic field from digital mobile telephones
  • Electrostatic Discharge testing (ESD)
