HVI VLF-65CMF Hipot Tester Repair
The HVI (High Voltage Inc.) VLF-65CMF is a 65 kV VLF (very-low-frequency) hipot test set — it applies 0.1 Hz high voltage to withstand-test and diagnose medium- and high-voltage cable insulation, including tan-delta diagnostics, where DC or power-frequency AC would be unsuitable. It combines a VLF HV source with leakage/diagnostic measurement, so faults span the HV side and the measurement side both.
June Company repairs and calibrates the HVI VLF-65CMF for cable-testing and utility crews.
Common HVI VLF-65CMF problems we fix
- HV output-stage failure — won’t reach VLF test voltage or output unstable, the HV stage repaired for stable rated output.
- VLF waveform faults — the 0.1 Hz waveform distorted or off-frequency, corrected.
- Tan-delta / leakage measurement off — the diagnostic measurement, recalibrated against standards.
- Internal HV arcing or leakage — insulation breakdown from stress.
- Control or interlock faults.
FAQs
My VLF-65CMF won’t reach voltage — repairable? Yes. HV output-stage faults are serviceable; we restore stable rated VLF output and recalibrate the measurement, with a NIST-traceable certificate.
Is the tan-delta function verified? Yes — diagnostic measurement and VLF output are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
