Omicron CMA 56 Amplifier Repair
The Omicron CMA 56 Amplifier 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 Omicron CMA 56 Amplifier 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 Omicron CMA 56 Amplifier problems we fix
- 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.
- 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.
FAQs
Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.
One channel is weak and the rest are fine. Repairable? Yes, and it is the most common fault on these. Amplifier output stages fail individually and are repaired at component level.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
