Kingsine K3066i Relay Test Set Repair
The Kingsine K3066i is a six-phase protective-relay test set — it generates precise voltages, currents, and phase angles (six current channels) to test and commission protective relays and schemes in substations. 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 Kingsine K3066i for protection engineers and relay-test crews.
Common Kingsine K3066i 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.
- Won’t connect to the control PC — interface faults, repaired.
- Display, control, or power faults.
FAQs
One of my K3066i 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.
