CIGRÉ considers collecting, analyzing and publishing reliability data to be important tasks and in 2002, WG A3.06 “Reliability of High Voltage Equipment” was established. The WG was instructed to organize and carry out a worldwide enquiry into the service experience of circuit breakers, disconnectors, earthing switches, instrument transformers and gas insulated switchgear (GIS). The time period covered by the survey is 2004 - 2007, and the enquiry comprises equipment rated for voltages greater than or equal to 60 kV. For circuit breakers: only single pressure SF6 technology is included ; therefore, in practice equipment installed before around 1970 has been excluded. For disconnectors, earthing switches and instrument transformers there are no limitations in age or technology. Both equipment installed in air insulated and gas insulated substations are covered. Information has been collected by asking utilities to complete and return questionnaires ; 90 utilities from 30 countries have contributed. The results of the survey are presented and discussed in six Technical Brochures, issued simultaneously. |
