VLF/THUMPER COMBO
VT-33(F)
Features and Benefits
The VT-33 is the combination VLF hipot and cable fault locator, or thumper. It is a complete tool for AC testing and fault locating cables rated up to 25 kV. It offers a 33 kV AC peak VLF output, VLF cable burn mode, and a 760 J discharge output up to 13 kV. It is also TDR/radar ready.
Features:
- TDR-ready, arc-reflection and current pulse methods
- Built in high voltage coupler for TDR interconnect
- Variable discharge rate
- High VLF burn current
- Portable, hand truck mounted
