Status: The HVI PTS Series DC hipot testers are in current production. We repair and calibrate all of them.
Common HVI PTS Series Problems We Fix
- Won’t reach test voltage / output low or unstable — HV multiplier stack failure after sustained testing or flashover
- Voltage won’t hold steady — voltage regulation circuit degradation
- Leakage current reading drifting or inaccurate — critical for cable pass/fail decisions
- HV cable or connector arcing / insulation breakdown
- Safety interlock won’t clear / won’t allow a test
- Cooling fan noisy or failed on higher-voltage models
- Control circuit faults or aging

Frequently Asked Questions
How much does HVI PTS 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 PTS repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast. High-voltage sets with multiplier-stack damage can run longer — we’ll tell you up front with the quote.
My tester won’t reach full test voltage — can you fix it?
Yes. HV multiplier stack failures from sustained testing or a flashover event are one of the most common faults on these testers, and they’re fully restorable to rated voltage.
The output won’t hold steady — is that repairable?
Yes. Voltage regulation circuit degradation that causes unstable or drifting output is a routine repair, restored for steady, continuously variable DC output.
My leakage current readings look off — can you recalibrate it?
Yes, and on DC cable testing this is the measurement that matters most. We recalibrate the leakage current and voltage metering against our reference standards and document the results on a NIST-traceable certificate.
I test cables and need clean DC for accurate leakage readings — can you service the filtered (F) models?
Yes. The F-suffix models add filtration for smoother DC output, which is what makes leakage current accurate on capacitive loads like cables. We repair and recalibrate the filtered output so those readings stay trustworthy.
Can you repair arcing HV cables or connectors?
Yes. High-voltage cable 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 PTS configuration, filtered F-models included. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the HVI PTS Series?
Electric utilities, cable testing contractors, transformer maintenance shops, switchgear testers, and industrial high-voltage maintenance programs rely on the PTS Series for DC dielectric withstand testing per IEEE and NETA standards.
