Description
Omicron CMC 500 Relay Test Set Repair Services
The Omicron CMC 500 is a critical instrument used by utility relay technicians, substation commissioning engineers, relay manufacturers, and industrial protection teams. When this equipment fails or drifts out of specification, June Company delivers expert repair and NIST-traceable calibration to restore full operational accuracy.
About the Omicron CMC 500
As a relay test set instrument, the Omicron CMC 500 is designed for demanding applications. Specifically, relay test sets generate precise voltage and current waveforms to test the operation and timing of protective relays used in power system protection schemes. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
Common Relay Test Set Issues We Repair
Our repair process addresses the root cause of every issue:
- Timing measurement drift: identified during our multi-point inspection and corrected to restore specification performance
- Phase angle accuracy errors: addressed with OEM-grade components and verified against traceable standards
- Communication module faults: repaired by technicians experienced with Omicron instrumentation
- Binary input/output failures: resolved through targeted diagnostics and precision repair techniques
- Output amplifier failure: diagnosed through systematic testing and resolved with component-level repair
Calibration and Performance Verification
After repair, we perform comprehensive calibration across all operational modes. For the Omicron CMC 500, this includes verification of phase angle and fault simulation performance, with results documented on a NIST-traceable calibration certificate.
