The work of the Study Committee is organized into equipment groups. Each of these is concerned with exchanging practice and experience on design, construction, test and behaviour of turbo-generators, hydro-generators, large motors and novel machines.

In order to respond to the future environment, a series of strategic directions are being followed. In the field of condition monitoring and diagnosis the process is one of continuous evolution and development. The main goal is the most effective operation of machines to optimise performance, reliability and efficiency and to set up maintenance decisions through a better understanding of behaviour and signs of deterioration, that is maintenance must be based on the condition of the machine, instead of the traditional time based approach. There is an important link between monitoring and diagnosis and the life management and the life extension processes.

Electrical Machine evolution cannot be divorced from the choice of fuel, methods of energy conversion, the closely related mechanical behaviour of prime mover turbines, pumps, fans etc and environmental issues. Work is being undertaken to ensure that future machines are capable of meeting envisaged system stability requirements.

The long-term evolution of system designs and future requirements need to be anticipated. A dialogue with System Committees has been established to foreshadow the System requirements and harmonise with machine capability.

System behaviour studies must include the relationship between electrical machine issues and the mechanical behaviour of closely coupled prime movers, as well as the overall representation of plants in order to better evaluate the overall system performance.
