Von Corp. B-.45 Hipot Tester Repair
The Von Corporation B-.45 is a high-voltage hipot/dielectric test set — Von Corp builds rugged HV test equipment for utility and apparatus testing, applying high voltage and measuring current/leakage to withstand-test insulation. It combines an HV source with metering, so faults span both the HV output and the measurement side.
June Company repairs and calibrates the Von Corp. B-.45 for utility and electrical-apparatus test crews.
Common Von Corp. B-.45 problems we fix
- Won’t reach test voltage or unstable — HV output-stage/transformer failure, repaired for stable rated output.
- Current/leakage metering off — the measurement your pass/fail depends on, recalibrated against standards.
- Voltage regulation drift — output won’t hold under load, corrected.
- Internal HV arcing or leakage — insulation breakdown from stress.
- Interlock or control faults.
FAQs
My B-.45 won’t reach voltage — repairable? Yes. HV output-stage faults are serviceable; we restore stable rated output and recalibrate the metering so your test results are accurate, with a NIST-traceable certificate.
Is the metering verified? Yes — checked against our standards along with the HV output.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
