CMC 850

Protection test set dedicated to IEC 61850

Compact Protection Test Set for Fully Digital Substations

The CMC 850 is a protection test set dedicated to IEC 61850. It focuses on the real-time communication methods GOOSE and Sampled Values to interface with the devices under test.

Like all other CMC test sets, the CMC 850 is controlled by OMICRON's proven Test Universe software. It also offers several embedded functions accessible through a Web interface by simply using a standard Web browser.

The CMC 850 is small and lightweight because its focus on IEC 61850 applications means there is no need for conventional binary I/Os and amplifiers for the secondary signals.


Protection Testing in Digital Substations

Testing "fully digital" protection relays
Perform testing with all applicable protection test modules of the OMICRON Test Universe. By mapping the I/Os to Sampled Values and GOOSE, all functions can be used as with conventional relays.
Emulating Merging Units
The CMC 850 injects up three (four when used with RelaySimTest) Sampled Value streams into the process bus.

Key features

  • Small and light weight because of its focus on IEC 61850 applications
  • Ready to go software: OMICRON Control Center, IEC 61850 configuration modules, IEDScout, etc.
  • To be used with the OMICRON Test Universe software and with RelaySimTest
  • 12 low level analog outputs, e.g. for stimulating devices with low level inputs
