What is BS EN 61377-2-2016?

BS EN 61377-2-2016 is a technical standard that provides guidelines for the protection of electronic equipment in railway applications against electrical disturbances and electromagnetic interference. It specifically addresses the requirements for power supply systems and equipment in those applications.

Scope and Application

The standard applies to all types of rolling stock, including locomotives, coaches, and wagons, as well as fixed installations along the railway track. It covers the electrical systems and components used for traction, auxiliary power, control, and communication purposes.

Furthermore, BS EN 61377-2-2016 also includes requirements for the testing and verification of compliance for the various types of equipment and systems it addresses. This ensures that the specified performance levels are met by the manufacturers.

Key Requirements and Testing Procedures

One of the main objectives of BS EN 61377-2-2016 is to ensure the reliable operation of electronic equipment in the presence of disturbances caused by the railway environment. To achieve this, the standard outlines specific requirements and testing procedures.

For example, it specifies the maximum allowable limits for conducted and radiated disturbances across different frequency bands. Manufacturers need to test their equipment to ensure that it meets these limits and remains unaffected by external interferences.

In addition, the standard addresses the protection of equipment against transient voltage disturbances, such as voltage spikes and surges. It defines the required voltage withstand levels and provides guidelines for testing methods.

Benefits and Impact

The implementation of BS EN 61377-2-2016 brings several benefits to the railway industry. Firstly, it enhances the reliability and safety of electronic equipment on board trains, reducing the risk of malfunctions due to electrical disturbances. This, in turn, improves overall system performance and passenger experience.

Moreover, adherence to this standard promotes interoperability between different railway systems and equipment from various manufacturers. It ensures that all electronic devices meet the same set of requirements and perform reliably in a shared environment.

In conclusion, BS EN 61377-2-2016 plays a crucial role in guaranteeing the proper functioning and protection of electronic equipment in railway applications. By establishing clear guidelines and testing procedures, it contributes to the smooth and safe operation of trains, benefiting both passengers and stakeholders in the industry.
