Abstract:

Electromagnetic compatibility is concerned with ensuring electronic and electrical equipment functions without interference due to £he electromagnetic disturbances generated by a device or present in the operating environment. Within the railway, traction power electronic equipment for example, should not interfere with the correct operation of trackside signaling equipment or with the on-board brake control and the telecommunication equipment. Outside the railway are the consumer equipment and the biomedical equipment near the rail viaduct. It is vital for safe operation that the signaling and the telecom equipment are not corrupted by electromagnetic inte1ference especially from the traction equipment. This paper deals with the preliminary equipment survey for possible effects of radiated electromagnetic inte1ference to the signaling equipment, CCTV monitors at the stations, hospital and university equipment that are located near the rail tracks. The results of the survey on the targeted areas shows that there exists no significant EMI pollution along the 10-meter vicinity of the track However, this result is tentative and may not be deemed conclusive. Recommendations on a comprehensive assessment of radiated EMI are presented.
