The OMICRON CMC 356 Advanced Protection Relay Test Set is a high-precision, six-phase current and four-phase voltage source engineered for secondary injection testing, commissioning, and maintenance of protection relays, energy meters, and instrument transformers. Available to rent or hire, it delivers the accuracy and output power needed by utility engineers, commissioning teams, and industrial plant technicians to validate protection schemes quickly and reliably.
Designed by OMICRON Energy, the CMC 356 combines robust output channels—6 × 32 A (128 A short-time) current and 4 × 300 V voltage—with class-leading amplitude and phase accuracy. Its integrated 10 binary inputs and 4 binary outputs simplify end-to-end automation tests, while GPS/IRIG-B/IEEE 1588 synchronisation enables precise time-aligned fault simulations. Operated via OMICRON’s Test Universe software or the on-board CMControl interface, the unit supports everything from simple overcurrent tests to complex distance, differential, and IEC 61850 GOOSE-based schemes.
Key Features:
- 6 × 32 A Current Outputs: High-power channels (430 VA each) handle electromechanical and modern numerical relays with ease.
- 4 × 300 V Voltage Outputs: Independent, high-accuracy sources for three-phase voltage plus auxiliary tasks such as synchronising checks.
- Wide Frequency Range: DC to 3 kHz programmable sweep supports generator, turbine, and frequency protection testing.
- Precision Timing & Sync: GPS, IRIG-B, and PTP options enable sub-microsecond time stamping for dynamic state-sequence tests.
- Integrated Binary I/O: 10 inputs and 4 outputs simplify logic, trip, and breaker-time measurements without external accessories.
- PC & Stand-Alone Control: Run automated scripts via Test Universe or quick manual tests with the touchscreen CMControl front panel.
