Sažetak
The 1st GIS international survey questionnaire was circulated in 1991 and both users and manufacturers were addressed. It collected experience up to 31.12.1990. 109 users from 34 countries and 18 manufacturers from 9 countries responded to the questionnaire. The user’s experience represented 1 817 GIS, 10 531 circuit breaker-bays (CB-bays) and 78 036 CBbay-years, the manufacturer’s experience represented 4 867 GIS, 24 870 CB-bays and 199 473 CB-bay-years. The questionnaire addressed: general data about GIS installations, factors which contributed to selection of GIS over AIS, adequacy of existing design/production/site test procedures, reliability, availability and maintainability, cause of major failures, future trends/condition monitoring /diagnostics and general open-ended questions. The survey and data analysis were published in CIGRE papers during 1992 to 1994. The 2nd GIS international survey questionnaire was circulated five years later, in 1996, with the aim of collecting service experience data available up to 31.12.1995. 80 users from 30 countries responded to the questionnaire. The collected data referred to 2115 GIS installations, 13 696 CB-bays and 118 483 CB-bay-years. In comparison to the 1st questionnaire, the 2nd questionnaire was more focused on installation overview and major failure statistics and GIS life cycle issues. Therefore only users were addressed. Besides the general data about GIS installations (similar to data sheet in the first survey) the users were asked to report the characteristics and service experience (major failures) for each individual GIS from the beginning of their putting into service and to answer more general questions concerning maintenance, lifetime and environmental aspects independently of the number of installed GIS and voltage level. The survey and data analysis were published in CIGRE papers during 1998 to 2000. The 3rd GIS international survey questionnaire was circulated in 2003 and collected population and failure data in 2004 to 2007. The structure of the questionnaire was as much as useful similar to the 2nd survey to enable a comparison.
