PD CLC/TS 50238-3 is a standard that covers the electromagnetic compatibility between rolling stock and axle counter detectors, enabling the prevention of interferences for stable operability in railway applications.
PD CLC/TS 50238-3 defines the interference limits for axle counter detectors and evaluation methods to verify rolling stock emissions for the purpose of demonstrating compatibility between rolling stock and axle counters.
PD CLC/TS 50238-3 gives recommended individual limits to be applied to establish compatibility between RST and all selected types of axle counter detectors, including several covered by national standards.
In PD CLC/TS 50238-3, the list of selected types of axle counter detectors and their limits for compatibility are drawn on the basis of established performance criteria.
Note 1: PD CLC/TS 50238-3 does not cover wheel sensors and crossing loops.
Note 2: PD CLC/TS 50238-3 does not cover the influences from metal parts or inductively coupled resonant circuits on the vehicle, eddy current brakes or magnetic brakes.
PD CLC/TS 50238-3 on electromagnetic compatibility between rolling stock and axle counter detectors is useful for:
EMC refers to the accidental generation, propagation, and receipt of electromagnetic energy, which can result in undesirable consequences like electromagnetic interference or even physical damage to operating equipment. EMC testing is mandatory for electrical measuring equipment such as insulation monitoring devices in order to meet all the regulatory EMC requirements for efficient and reliable performance.
PD CLC/TS 50238-3 provides you with a set of interference limits for magnetic fields resulting from both rail current and equipment onboard the vehicles, enabling you to create an environment that is not susceptible to interferences.
PD CLC/TS 50238-3 provides you guidance on the evaluation criteria to verify rolling stock emissions and demonstrate compatibility with the interference limits for magnetic fields to ensure compatibility with EMC requirements.
Adoption of PD CLC/TS 50238-3, aids railway management system and regulatory authorities as it sets the interference limits and evaluation criteria for electromagnetic compatibility between rolling stock and axle counter detectors for hazard prevention, resilience and safety in railway applications.
