HVI VLF-6022CM Hipot Tester Repair
The HVI VLF-6022CM is a 60 kV VLF cable hipot from High Voltage Inc. — a higher-voltage withstand tester for medium- and sub-transmission-class cable at 0.1 Hz. At 60 kV the output stage works harder, which is where most faults originate.
June Company repairs and calibrates the VLF-6022CM for cable-testing crews on higher-voltage cable.
Common VLF-6022CM problems we fix
- Won’t reach 60 kV or output collapses — VLF output-stage failure, often post-flashover, rebuilt.
- Waveform distorted or unstable — regulation degradation, repaired to spec.
- Metering off — voltage/leakage measurement drift, recalibrated.
- Internal HV arcing — insulation breakdown from stress.
- Control or interlock faults.
FAQs
My VLF-6022CM won’t hold 60 kV — repairable? Yes. VLF output-stage faults are repairable, then verified so the set delivers full, stable output again, with a NIST-traceable certificate.
Is the metering certified? Yes — verified against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
