Description

HVI VLF-50CMF Hipot Tester Repair

The HVI VLF-50CMF is a 50 kV sinusoidal VLF cable hipot from High Voltage Inc. — the “F” denotes its filtered true-sine 0.1 Hz output, which meets IEEE 400.2 sine-wave withstand requirements for medium-voltage cable. Its faults concentrate in the VLF generator that has to hold a clean sine, plus the control system.

June Company repairs and calibrates the VLF-50CMF for cable contractors and utilities running sine-wave VLF tests.

Common VLF-50CMF problems we fix

  • VLF generator output failure — won’t reach 50 kV or the sine collapses, rebuilt for full clean output.
  • Control system faults — the control electronics not sequencing the test, repaired.
  • Waveform distortion — regulation faults degrading the true-sine output, corrected to spec.
  • Metering drift — voltage/leakage measurement recalibrated.
  • Internal HV arcing or interlock faults.

FAQs

My VLF-50CMF sine looks distorted — fixable? Yes. Waveform distortion traces to the VLF generator or regulation; we repair it so the 0.1 Hz sine meets IEEE 400.2, verified with a NIST-traceable certificate.

Are control faults covered? Yes — the control system is repaired and verified along with the HV output.

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.
