What is IEC 60077-2:2012 ?

IEC 60077-2:2012 is an essential standard for the electrical equipment used in rolling stock in the railway industry. It provides a detailed guide for the design, construction, and testing of control gear and related devices, covering various aspects such as electrical, mechanical, environmental, and thermal properties.

The standard is widely recognized for ensuring the safety, efficiency, and interoperability of electrical equipment in railway systems. It ensures that the control gear used in alternating current (AC) systems with rated voltages not exceeding 3,000 volts meets certain requirements, promoting the safety of both passengers and railway personnel.

IEC 60077-2:2012 promotes interoperability by providing a common framework for control gear manufacturers and suppliers. This allows for seamless integration and compatibility between different rolling stock components from various manufacturers, reducing the need for costly customizations or modifications when incorporating electrical equipment into railway systems.

Classification of control gears

The standard defines different classes of control gears, each suitable for specific types of rolling stock. These classes include control gears for locomotives, passenger coaches, and freight wagons, among others. The classification is based on the maximum voltage and current ratings of the control gear, as well as the operating speed and the number of poles.

The standard provides a detailed guide for manufacturers and suppliers to ensure that their products meet the requirements of the classification system. This ensures that different types of rolling stock can use the same or compatible control gear, promoting compatibility and reducing the need for customizations or modifications.

Conclusion

In conclusion, IEC 60077-2:2012 is an essential standard for the electrical equipment used in rolling stock in the railway industry. It ensures the safety, efficiency, and interoperability of control gear and related devices, while promoting compatibility and reducing the need for customizations or modifications. Compliance with the standard is widely recognized as a mark of quality and safety, ensuring that rolling stock is safe, reliable, and efficient.
