Baur PHG 70 TD/PD VLF Tester Repair
The Baur PHG 70 TD/PD is a 70 kV VLF cable test set with full diagnostics — withstand testing, tan-delta loss measurement, and partial-discharge detection in one system. Like its 80 kV sibling, its faults can come from the HV source, the tan-delta path, or the sensitive PD detection.
June Company repairs and calibrates the PHG 70 TD/PD for advanced cable-diagnostics teams and utilities.
Common PHG 70 TD/PD problems we fix
- Partial-discharge detection faults — sensitivity or accuracy loss in the PD measurement, repaired and recalibrated.
- Tan-delta drift — loss-measurement recalibration against standards.
- Won’t reach 70 kV / output collapses — HV output-stage rebuild, often post-flashover.
- Test-port or HV-cable damage — replaced.
- Display, battery, or control faults.
FAQs
My TD/PD results look wrong — repairable? Yes. We isolate which function drifted — tan-delta or PD — repair and recalibrate it, and verify the HV withstand side, with a NIST-traceable certificate.
Is the full diagnostic suite verified? Yes — withstand, tan-delta, and PD are all checked.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
