Description
HV Diagnostics HVA120 Hipot Tester Repair
The HV Diagnostics HVA120 Hipot Tester is a hipot tester – it applies a high AC or DC voltage across insulation and watches the leakage current for a breakdown. It is a safety instrument, which changes the stakes on its accuracy: a tester that quietly under-delivers voltage passes everything put in front of it.
June Company repairs and calibrates the HV Diagnostics HVA120 Hipot Tester for production test departments, electrical safety teams, panel builders, and compliance laboratories. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common HV Diagnostics HVA120 Hipot Tester problems we fix
- Test voltage low or not reaching setpoint – the most consequential fault on a safety tester, because under-voltage produces a pass on equipment that should have failed and nothing on the display indicates it.
- Leakage current measurement inaccurate.
- Arc detection not triggering or triggering falsely.
- High-voltage transformer or output stage faults.
- Safety interlock or ground-continuity circuit failure.
- Ramp and dwell timing errors.
- HV lead, probe or connector damage.
- Display, keypad or front-panel faults.
- GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
FAQs
What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
It passes everything I test. Is that suspicious? It can be. An under-delivering hipot passes equipment that should fail, and that is exactly the failure mode worth ruling out.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. 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.
