User guide for the application of monitoring and diagnostic techniques for switching equipment for rated voltages of 72.5 kV and above

Condition monitoring and diagnostic techniques are playing an increasingly important role in the design, life cycle cost evaluation, commissioning, operation, maintenance and end of life determination of substation equipment. Users need guidance on the applicability and implications of the various techniques and how their benefits can be evaluated.The report gives guidelines for the application of monitoring and diagnostic techniques covering all switching technologies and including disconnectors and earthing switches as well as circuit-breakers.
