Analysis covers measurement and simulation methods, identification of quality indices, monitoring techniques, emission from disturbing installations, immunity of sensitive installations, and mitigation techniques. Electromagnetic Compatibility (EMC): high frequency disturbances on the electricity supply and all disturbances (HF or LF) reaching equipment other than through the electricity supply. Studies include measurement and simulation methods. Health effects related to low frequency EMF are however excluded. Power System Security Assessment: development of new analytical techniques for assessment of power system security, design of controls and modelling of existing and new equipment, real time stability evaluation and control Lightning: analysis of lightning characteristics and interactions of lightning with electric power systems and equipment, including protection in MV and LV networks against lightning, and their standardization. Insulation co-ordination: methods and tools for insulation coordination in electric power systems and equipment, contributing to optimisation of their cost and reliability.
