HVI PAR Series AC Dielectric Tester Repair

Status: Current Production. We repair and calibrate all of them.

Common HVI PAR Series Problems We Fix

  • Won’t reach test voltage / output collapses under load — HV output transformer insulation failure
  • Can’t hold voltage on capacitive loads / charging current limited — power supply degradation under heavy cycling
  • Output won’t adjust smoothly / arcs at the dial — voltage regulator contact degradation
  • Voltage or current reading drifting or inaccurate — metering drift
  • HV bushing or connector arcing / insulation breakdown
  • Cooling system noisy or failed — critical on high-power models
  • Control circuit faults

Frequently Asked Questions

How much does HVI PAR Series repair cost?

Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.

How long does the repair take?

Most HVI PAR repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast. High-power sets with transformer damage can run longer — we’ll tell you up front with the quote.

My set won’t reach voltage or collapses under load — can you fix it?

Yes. HV output transformer insulation failure from sustained high-power testing is one of the most common faults on these sets, and it’s fully restorable to rated voltage and power.

It can’t hold voltage when testing a large capacitive load — is that repairable?

Yes. These sets are built for high charging current, and power supply degradation under heavy load cycling that limits that capacity is repairable, restored so the set drives transformers, switchgear, and bus duct as intended.

My voltage or current readings look off — can you recalibrate it?

Yes. We recalibrate the voltage and current metering against our reference standards and document the results on a NIST-traceable certificate.

The cooling system failed — can you repair it?

Yes. Cooling system faults are repairable, and they matter most on the high-power PAR models where adequate cooling is critical to sustained testing — we restore it to keep the set within its thermal limits.

Can you repair arcing HV bushings or connectors?

Yes. High-voltage bushing and connector insulation breakdown that causes arcing is repairable, restored for safe, reliable high-voltage testing.

What if my exact model isn’t listed?

We service every HVI PAR configuration, including the FC5 full-cycle five-step models. If your model isn’t in the table, pick the closest match or email us — the process is the same.

Who uses the HVI PAR Series?

Transformer manufacturers, switchgear factories, utility commissioning teams, electrical testing laboratories, and large industrial maintenance programs rely on the PAR Series for high-power AC dielectric testing of major electrical apparatus.
