Status: Current Production. We repair and calibrate all of them.
Common HVI PFT Series Problems We Fix
- Won’t reach test voltage on AC or DC / output low or unstable — HV transformer or multiplier stack failure
- Won’t switch between AC and DC / one mode dead — AC/DC switching relay contact wear
- Voltage or current reading drifting or inaccurate — metering drift
- Megohmmeter / insulation resistance function not working
- HV cable or connector arcing / insulation breakdown
- Panel switches or indicators not responding
- Guard terminal circuit faults affecting leakage readings

Frequently Asked Questions
How much does HVI PFT 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 PFT repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My tester won’t reach voltage on AC or DC — can you fix it?
Yes. HV transformer and multiplier stack failures that cause low, unstable, or missing output on either mode are among the most common faults on these testers, and they’re fully restorable to rated voltage.
One mode works but it won’t switch between AC and DC — is that repairable?
Yes. AC/DC switching relay contact wear that leaves one mode dead or makes switching unreliable is a routine repair, restored so both functions work as intended.
The megohmmeter function isn’t working — can you fix that?
Yes. These combine AC hipot, DC hipot, and insulation resistance in one instrument, and megohmmeter measurement circuit faults are repairable so all three functions are restored.
My voltage or current readings look off — can you recalibrate it?
Yes. We recalibrate the voltage and current metering across both AC and DC against our reference standards and document the results on a NIST-traceable certificate.
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 PFT configuration, including the CM combined-meter, CE/CEF enhanced, and 503DBT digital-DC variants. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the HVI PFT Series?
Electric utilities, NETA-certified testing companies, cable testing contractors, switchgear commissioning crews, and industrial electrical maintenance teams rely on the portable PFT testers for field acceptance and maintenance testing of cables, switchgear, and transformers.
