sf 6-insulated HV Test-Transformer Systems

6 insulated test transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and on-site, and for testing on-site substation equipment. The conventional transformers can be flanged directly to the GIS. This makes testing of such GIS installations possible without feeding them through an air-SF 6 bushing. Therefore, the merits of the
