Baur PGK 150 HB High Voltage Tester Repair
The Baur PGK 150 HB is a 150 kV VLF (0.1 Hz) high-voltage cable test set — used to withstand-test and diagnose higher-class medium- and sub-transmission-voltage cable without the space-charge problems of DC hipot. At 150 kV the HV output stage works hard, which is where most faults originate.
June Company repairs and calibrates the PGK 150 HB for cable-testing contractors and utilities on higher-voltage cable.
Common PGK 150 HB problems we fix
- Won’t reach 150 kV or output collapses — HV output-stage failure, often after a cable flashover, rebuilt for full VLF output.
- Waveform distorted or unstable — regulation degradation on the 0.1 Hz output, repaired to spec.
- Voltage/leakage metering off — measurement drift, recalibrated.
- Internal HV arcing — insulation breakdown from cumulative stress.
- Control or interlock faults.
FAQs
My PGK 150 won’t reach voltage after a flashover — fixable? Yes. HV output-stage damage from a flashover is the most common fault and it’s repairable, then verified so the set delivers a clean full-voltage VLF waveform again.
Is the output certified? Yes — voltage and frequency verified with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
