Product Description
680kVA 270kV Variable Frequency AC Resonant Test System
This 680kVA 270kV Variable Frequency AC Resonant Test System is intended for specified high-voltage AC withstand voltage testing of compatible capacitive electrical equipment. The stated ratings provide a starting point for technical assessment, while final equipment selection depends on the test-object capacitance, required test voltage, operating frequency, test duration, installation environment, and applicable test specification.
Gas-insulated switchgear (GIS) are relevant application categories for consideration in high-voltage testing projects, including projects associated with 110kV and 220kV systems. The requirements for a GIS installation can differ according to equipment design and project specifications, so the system configuration should be confirmed before ordering. Sansion Power can review the proposed test object and discuss the required reactor arrangement, variable-frequency power supply, excitation transformer, voltage measurement, control functions, and agreed accessories. Partial discharge diagnosis, where required, should be identified separately and verified as part of the confirmed measurement scope.
