Status: Current Production. We repair and calibrate all of them.
Common HVI HPA / ABT Series Problems We Fix
- Won’t reach test voltage / output low or unstable — HV output transformer insulation degradation
- Output won’t adjust smoothly / jumps or arcs at the dial — variac contact wear
- Voltage or current reading drifting or inaccurate — metering transformer or shunt drift
- Trips on overload unexpectedly / won’t trip when it should — overload protection faults
- HV bushing or connector arcing / insulation breakdown
- Cooling system noisy or failed on higher-power models
- Control circuit faults or aging

Frequently Asked Questions
How much does HVI HPA / ABT 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 HPA / ABT 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 full test voltage — can you fix it?
Yes. HV output transformer insulation degradation that causes low, unstable, or missing output is one of the most common faults on these sets, and it’s fully restorable to rated voltage.
The output won’t adjust smoothly or arcs at the dial — is that repairable?
Yes. Variac contact wear from continuous voltage adjustment is a routine repair, restored for smooth, continuously variable output.
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.
It trips on overload when it shouldn’t — can you fix the protection circuit?
Yes. Overload protection circuit faults that cause nuisance trips, or fail to trip when they should, are repairable and restored to proper protective operation.
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 HPA and ABT configuration, including the FC full-cycle and combined-meter 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 HPA / ABT Series?
Electric utilities, electrical testing laboratories, switchgear manufacturers, transformer test shops, and industrial commissioning teams rely on the HPA and ABT sets for power-frequency AC withstand and dielectric breakdown testing.
