Specification :

Mode: HGTS serial
Sf6 Insulated
Voltage: 20kV - 1000kV

APPLICATION
SF6-Insulated HV Test Transformer System is designed for high voltage high capacitance metal-clad switchgear ( GIS) in the factory and on-site withstand test, partial discharge test and GIS instrument transformer accuracy test, such as GIS transition station, disc insulator manufacturer. The conventional transformers can be flanged directly to the GIS. This makes testing of such GIS installations possible without feeding them through an air-SF6 bushing. These systems are particularly suited for on-site tests of GIS after assembly. In the factory, they allow to test sub-assemblies and components directly in the manufacturing line, thus avoiding transportation to a central test facility, and extra handling.
