Baur PHG 80 VLF Tester Repair
The Baur PHG 80 is an 80 kV VLF (0.1 Hz) high-voltage cable test set — used to withstand-test medium-voltage cable insulation without the space-charge problems of DC hipot. As an HV-generation instrument, its faults concentrate in the output stage, regulation, and metering.
June Company repairs and calibrates the PHG 80 for cable-testing contractors and utility crews.
Common PHG 80 problems we fix
- Won’t reach 80 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 stress.
- Control or interlock faults.
FAQs
My PHG 80 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 it 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.
