Description
SMC Quasar Relay Tester Repair
The EuroSMC Quasar is a three-phase protective-relay test set — it generates precise voltages, currents, and phase angles to test and commission protective relays and schemes. As a high-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 Quasar for protection engineers and relay-test crews.
Common SMC Quasar problems we fix
- Output-amplifier rebuilds — a voltage or current channel weak or dead, repaired so every channel meets rated output.
- Timing-system recalibration — trip-time and timing drift, recalibrated against standards.
- Phase-angle accuracy off — the phase reference drifting, corrected.
- Won’t connect to the control PC — interface faults, repaired.
- Display, control, or power faults.
FAQs
One of my Quasar channels is down — fixable? Yes. Amplifier output-stage failure is a common fault and it’s repairable, then all channels 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.
