Description

HVI VLF-28CM Hipot Tester Repair

The HVI VLF-28CM is a 28 kV VLF (0.1 Hz) cable hipot from High Voltage Inc. — a compact withstand tester for medium-voltage cable that avoids the space-charge problems of DC testing. As an HV-generation set, its faults are VLF output, regulation, and metering faults.

June Company repairs and calibrates the VLF-28CM for cable-testing crews and contractors.

Common VLF-28CM problems we fix

  • Won’t reach 28 kV or output collapses — VLF generator/output-stage failure, often post-flashover, rebuilt for full output.
  • Waveform distorted or unstable — regulation degradation on the 0.1 Hz output, repaired.
  • Voltage/leakage metering off — measurement drift, recalibrated.
  • Internal HV arcing — insulation breakdown from stress.
  • Control or interlock faults.

FAQs

My VLF-28CM won’t reach voltage — fixable? Yes. VLF generator faults are the usual cause and they’re repairable, then verified so the set delivers full, stable 0.1 Hz output again.

Is the output certified? Yes — voltage and frequency verified with a NIST-traceable certificate.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
