Kingsine KS1212 Standard Source Repair
The Kingsine KS1212 Standard Source is a protective relay test set – it generates precisely controlled voltages and currents, and times how a protection relay responds. High-current amplifiers driven hard into inductive loads are the heart of it, and the part that wears.
June Company repairs and calibrates the Kingsine KS1212 Standard Source for utility relay technicians, substation commissioning crews, and industrial protection teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Kingsine KS1212 Standard Source problems we fix
- One current or voltage channel weak or dead – amplifier output-stage failure in a single channel while the others still work, which is the classic giveaway.
- Phase angle accuracy drifted.
- Trip timing measurement errors.
- Binary input or output faults.
- IEC 61850 or GOOSE communication failures.
- Convertible channels not combining.
- Cooling fan or thermal shutdown.
- Internal power supply faults.
- Display, keypad or front-panel faults.
