IEC 60308:2005

Defines the terms and quantities necessary to describe the regulating behaviour of the speed governing system. It presents methods of testing and ways of measuring the quantities involved so that the performance and behaviour of the governing system can be ascertained and the guarantees verified.

IEC 60308:2024 deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices. The significant technical changes introduced by the third edition are the adoption of parts of IEC 61362:2024 which deal with test matters and the introduction of new technical aspects.
