The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands.
The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
The CMC 356 is the top choice for applications which require the highest level of versatility, output amplitude, and power. It has six powerful current sources, with great dynamic range, making the test set a universal solution for testing all generations and types of protection relays – from high burden electromechanical to IEC 61850 compatible relays. Commissioning engineers will particularly appreciate its ability to validate the correct wiring of current transformers, as well as ratio measurements through primary injection of high currents up to 128 A.
| Key Features |
| Powerful current sources for testing even high-burden electromechanical relays |
| High current amplitudes for 5 A relay testing |
| High accuracy and versatility for testing static and numerical relays of all types |
| Integrated network for testing IEC 61850 IEDs |
| 10-channel analog measurement and transient recording functionality (option) |
| Benefits |
|
| Safe and Future-Proof | The six current and four voltage output channels of the CMC 356 are continuously and independently adjustable in amplitude, phase and frequency. All outputs are protected against over-temperature, accidental short-circuits, external high-voltage transient signals and are monitored in case of overload.
The integrated network interface supports comprehensive testing in IEC 61850 environments using optional GOOSE simulation and subscription as well as Sampled Values simulation functionality. It is also possible to retrieve, evaluate and log the IED Client/Server SCADA communication according to IEC 61850.
|
| Varied Applications | By utilizing the EnerLyzer software option, the ten binary inputs of the CMC 356¹ can also function as analog measurement inputs.
The test set can then be used as a portable 10-channel multimeter, transient and trend recorder, harmonic signal analyzer and much more.
Up to 12 independent channels of low-level signals are available on the rear of the test set, which can be used to test relays with non-conventional sensor inputs (for example, Rogowski coils) or to control external amplifier units.
|
| Connectivity Options | The CMC 356 is designed to work with OMICRON’s most powerful software tools.
Users can control the test set using either a Windows PC/laptop or an Android tablet and connect via Ethernet/USB cable or Wi-Fi (through the optional mini wireless USB adapter).
Time synchronized applications according to IEEE 1588 are possible, for example, via CMGPS 588.
The GPS controlled time reference with integrated antenna works as a Precision Time Protocol (PTP) grandmaster clock and is optimized for outdoor usage.
|
| Organize your Tests | For centralized planning, tracking and managing of all engineering, testing and maintenance activities in the power industry, the ADMO software² ensures that the workflows of asset and operations managers, testers, and protection engineers are structured and coordinated.
Key data will be kept up-to-date and available to all employees at all times.
