Baur PGK 70 HB High Voltage Tester Repair
The Baur PGK 70 HB is a 70 kV VLF (very low frequency) high-voltage cable test set — it applies a 0.1 Hz sinusoidal high voltage to withstand-test and diagnose medium-voltage cable insulation without the space-charge problems of DC hipot. As HV-generation equipment, its faults are HV output-stage, regulation, and metering faults.
June Company repairs and calibrates the PGK 70 HB for cable-testing contractors and utility crews.
Common PGK 70 HB problems we fix
- Won’t reach 70 kV or output collapses — HV output-stage failure, often after a cable flashover, rebuilt for full VLF output.
- Waveform distorted or unstable — regulation degradation distorting the 0.1 Hz waveform, repaired to spec.
- Leakage/voltage metering off — measurement drift, recalibrated.
- Internal HV arcing — insulation breakdown from stress.
- Control or interlock faults.
FAQs
My PGK won’t reach voltage after a flashover — fixable? Yes. HV output-stage damage from a flashover is the most common PGK 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.

Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
