HV Diagnostics HVA68-2 Hipot Tester Repair
The HV Diagnostics HVA68-2 is a 68 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 HV Diagnostics HVA68-2 for cable-testing and utility crews.
Common HV Diagnostics HVA68-2 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 HVA68-2 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.

HV Diagnostics Repair
HV Diagnostics (HVD) specializes in manufacturing high-voltage diagnostic test equipment primarily used in the maintenance and testing of high-voltage electrical assets. Some of their key products and their functionalities include:
Partial Discharge (PD) Measurement Systems: These systems detect and measure partial discharges within insulation materials of high-voltage equipment. PD testing helps identify potential insulation weaknesses or faults before they lead to failures.
Tan Delta Measurement Systems: Used to measure the dielectric dissipation factor (tan delta) of insulation materials. This measurement helps assess the condition of insulation and detect early signs of deterioration.
Cable Fault Locators: Instruments designed to pinpoint faults and defects in underground cables. They help locate the exact location of faults without the need for extensive excavation, reducing downtime during repairs.
VLF (Very Low Frequency) Test Systems: Used for high-voltage testing of cables and other electrical equipment at frequencies typically between 0.1 Hz and 1 Hz. VLF testing assesses the integrity and condition of insulation under stress, helping predict potential failures.
Transformer Diagnostic Systems: Equipment designed to assess the condition of transformers through various tests such as insulation resistance, transformer turns ratio, and oil testing. These diagnostics help ensure the reliability and longevity of transformers in power distribution networks.
High-Voltage Testing Accessories: HVD also offers a range of accessories and software solutions that complement their diagnostic systems, enhancing the usability and efficiency of high-voltage testing and maintenance procedures.
Overall, HV Diagnostics products are essential tools for utilities, industrial facilities, and service providers involved in the maintenance and reliability testing of high-voltage electrical equipment and systems. They contribute to improving safety, reliability, and efficiency in electrical power networks and installations.
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.
