SMC PTE-50-CE-PRO Relay Test Set Repair
The EuroSMC PTE-50-CE-PRO is a portable protective-relay test set — it generates precise voltages, currents, and phase angles to test and commission protective relays and schemes in substations, in a rugged portable case. As a precision multi-phase test source, its faults split between the amplifier/output side and the timing/control side.
June Company repairs and calibrates the SMC PTE-50-CE-PRO for protection engineers and relay-test crews.
Common SMC PTE-50-CE-PRO problems we fix
- A voltage or current channel weak/dead — amplifier output-stage failure, repaired so every channel meets rated output.
- Timing / trip-time drift — the timing reference drifting, recalibrated against standards.
- Phase-angle accuracy off — the phase reference, corrected.
- Control / communication faults — won’t connect to or drive from the controller, repaired.
- Display, control, or power faults.
FAQs
One of my PTE-50 channels is down — fixable? Yes. Amplifier output-stage failure is a common fault and it’s repairable, then all channels and timing are verified against our standards with NIST-traceable calibration.
Is timing accuracy verified? Yes — timing and phase are checked and certified.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
