Getting under control the ageing of static protection relays
Protection relays of the Ultra High Voltage grid systems were built with electronic components since the years 1975. Afer 30 years in service, some components present ageing problems : the failure modes, unknown when the design has been done, caused some incidents on the grid systems. An organization method is proposed to put under control these risks. The analyses of the functional chains were carried out on protections, the trips of which have the greatest impacts f l y the number and functionality), in order to connect the principal component failures with their consequences on grid system operation. Simple measurements are proposed, as well as research ways on the phenomena causing these ageings.
