Variable Frequency AC Resonant Test System

Variable frequency AC resonant test systems are mainly used for AC withstand voltage test of large capacitive test objects on site. The test objects include SF6 circuit breakers, GIS, power cables, tec.
With suitable tuning capacitor, the frequency range can be from 20Hz to 300Hz. The AC resonant test systems are applicable for partial discharge test of instrument transformers, coupling capacitors and metal oxide surge arresters with rated voltage under 1000kV.

Features & Benefits
  1.  Compact design with light weight
  2. High quality factor/High Q value
  3. Variable frequency range from 20Hz to 300Hz
  4. Low power d emand due to high quality factor, the input power demand is just 1/Q of the output power capacity
  5. No transient over voltage during flashover of the test object
  6.  Lowest partial discharge value
Applications
  1. Onsite GIS testing;
  2. Power cable testing;
