Baur PHG 70 TD Diagnostic Tester Repair
The Baur PHG 70 TD is a 70 kV VLF cable test set with integrated tan-delta (TD) diagnostics — it doesn’t just withstand-test cable, it measures dielectric loss to assess the insulation’s actual condition and aging. Combining an HV source with a precision tan-delta measurement means its faults span both the HV side and the sensitive loss measurement.
June Company repairs and calibrates the PHG 70 TD for cable-diagnostics specialists and utility crews.
Common PHG 70 TD problems we fix
- Tan-delta readings off — drift in the loss-measurement circuit, the diagnostic heart of this set, recalibrated against standards.
- Won’t reach 70 kV or output collapses — HV output-stage failure, often post-flashover, rebuilt.
- Waveform distortion — regulation faults on the 0.1 Hz output, corrected.
- Voltage metering drift — recalibrated.
- Internal HV arcing or interlock faults.
FAQs
My tan-delta numbers look wrong — fixable? Yes. TD accuracy drift traces to the loss-measurement circuit; we repair and recalibrate it so cable condition assessments are trustworthy, with a NIST-traceable certificate.
Is the HV side verified too? Yes — withstand output is checked along with the diagnostics.
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.
