HV AC Series Resonant Test Systems

The HV AC Series Resonant Test System is a compact and modular solution for high-voltage withstand testing on cables, generators, transformers, and GIS. With its flexible tuning methods and scalable design, it is capable of handling large capacitive loads using lower input power, making it highly efficient for both routine and type testing.
