Description
HVI VLF-12011CMF Hipot Tester Repair
The HVI VLF-12011CMF is a 120 kV sinusoidal VLF cable hipot from High Voltage Inc. — a high-voltage true-sine (filtered) 0.1 Hz withstand set for higher-class cable, meeting IEEE 400.2 sine-wave requirements. At this voltage and with a clean-sine requirement, the VLF generator and control system carry significant stress.
June Company repairs and calibrates the VLF-12011CMF for utilities and contractors on high-voltage cable testing.
Common VLF-12011CMF problems we fix
- Won’t reach 120 kV or sine collapses — VLF generator/output-stage failure, rebuilt for full clean output.
- Waveform distortion — regulation faults degrading the true-sine output, corrected to IEEE 400.2.
- Control system faults — the control electronics, repaired.
- Metering drift — recalibrated to spec.
- Internal HV arcing or interlock faults.
FAQs
My VLF-12011CMF won’t reach voltage after a flashover — fixable? Yes. HV output-stage damage from a flashover is the most common fault; we rebuild it so the set delivers full 120 kV sine output, verified with a NIST-traceable certificate.
Is the sine waveform checked? Yes — verified against IEEE 400.2 tolerances.
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.
