TRANSORFILTER high-voltage switchgear leakage and quality

FunctionsSafetyPurposeCertificationsGoalsSummaryDiagnosisFeaturesSecurityIssuesScopeResultsPerformancePreventionSubstations and switchgear in an electrical system perform the functions of voltage transformation, system protection, power factor correction metering, and circuit switching. Electrical power aparatus, such as transformers, regulators, air switches, circuit breakers, capacitors, and lightning arresters comprise the components necessary to perform these functions.See more on testguy.net[PDF] High Voltage Circuit Breakers ... voltage switchgear supplied by Siemens today has an ex-pected lifetime of up to 50 years and maintenance intervals in the order of 20 to 25 years. The mean-time-between-major-failures (MTBF) is in the range of several thousand years (Figure 7). This high reliability must be considered as an important contribution to high quality power supply.
