Baur PGK 260 HB High Voltage Test Set Repair
The Baur PGK 260 HB is the highest-voltage member of the PGK VLF line at 260 kV — used for withstand-testing and diagnosing transmission-class cable at 0.1 Hz, where only the largest VLF sets reach. At this voltage the HV section, insulation, and control systems operate at the top of their stress range.
June Company repairs and calibrates the PGK 260 HB for utilities and specialist contractors testing transmission-class cable.
Common PGK 260 HB problems we fix
- Won’t reach 260 kV or collapses under load — HV output-stage failure on the highest-voltage unit, rebuilt for full output.
- Internal HV arcing or leakage — insulation breakdown, which matters most at this voltage class, repaired and verified.
- Waveform distortion — regulation faults on the 0.1 Hz output, corrected.
- Metering drift — recalibrated to spec.
- Control or interlock faults.
FAQs
My PGK 260 arcs internally or won’t hold voltage — fixable? Yes. At 260 kV, insulation and output-stage faults are the priority; we repair them and verify clean, safe full-voltage output before return.
Is the HV section certified safe? Yes — insulation integrity and output verified with documented results.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
