SPI225. Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker.

AbstractIntroductionTest SetupExperimental ResultsConclusionSulphur hexafluoride (SF6) gas and SF6 gas mixtures are widely used in gas insulated systems (GIS) because they have good dielectric and thermal properties. Among the various gas mixtures investigated so far, SF6 air, SF6 CO2, and SF6 N2 are most used gas mixtures. Also, these mixtures have much technical superiority in GIS. These are nontoxic and nonflammable gases, and they have less sensitivity to nonuniformities and higher liquefaction temperature at high pressure. GIS, switchgears, circuit break…See more on hindawiDiagnostic efficacy of SonoVue pubmed.ncbi.nlm.nih.gov/10997347SonoVue is a second generation ultrasound contrast agent consisting of phospholipid stabilized microbubbles filled with sulfur hexafluoride, with outstanding stability and resistance to pressure.
