Description
Kingsine KS813 Calibrator Repair
The Kingsine KS813 is a three-phase protection-relay test and calibration source — it generates precise voltages, currents, and phase angles to test and calibrate protective relays, meters, and instrument transformers. As a precision multi-phase source, its faults concentrate in the output amplifiers, the phase/timing reference, and the control electronics.
June Company repairs and calibrates the Kingsine KS813 for relay-test, metering, and calibration teams.
Common Kingsine KS813 problems we fix
- A voltage or current channel weak/dead — output-amplifier failure, repaired so every channel meets rated output.
- Phase-angle or timing accuracy off — the phase/timing reference drifting, recalibrated against standards.
- Output accuracy out of spec — measurement/source drift, recalibrated.
- Won’t connect to the control PC — interface faults, repaired.
- Display or control faults.
FAQs
My KS813 phase or output is off — fixable? Yes. Amplifier and phase-reference faults are repairable, then recalibrated so the source is accurate for relay and meter testing, with a NIST-traceable certificate.
Are all channels verified? Yes — voltage, current, and phase are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
