Phenix Technologies PM15-4A Insulation Analyzer Repair
The Phenix PM15-4A is a high-voltage insulation/megohmmeter analyzer — it applies high DC test voltage and measures insulation resistance (and diagnostic ratios like PI/DAR) on motors, cables, and transformers, with the rugged HV section Phenix is known for. The hardworking part is the high-voltage generator, so that’s where most faults originate.
June Company repairs and calibrates the Phenix PM15-4A for motor shops, cable contractors, and transformer-service teams.
Common Phenix PM15-4A problems we fix
- HV generator faults — won’t reach the selected test voltage or output is low, rebuilt for full rated voltage.
- Measurement drift — insulation-resistance readings drifting or unstable, recalibrated against standards.
- PI/DAR diagnostic ratios not calculating — the timed-test functions, restored.
- Guard-circuit faults — guard terminal damage affecting accuracy, repaired.
- Display or control faults.
FAQs
My PM15-4A won’t reach test voltage — fixable? Yes. HV generator faults are the usual cause and they’re repairable, then verified so the analyzer delivers full rated voltage and your readings are valid, with a NIST-traceable certificate.
Are the diagnostic ratios verified? Yes — PI and DAR are checked along with recalibration.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
