Omicron, a specialist in power system protection testing, now offers a new protection test set dedicated to IEC 61850. The new CMC 850 focuses on the real-time communication methods of GOOSE and Sampled Values to interface with test objects.
The new test set is very small and lightweight since there is no need for conventional binary inputs/outputs or amplifiers for the secondary signals. Despite its small size it provides two Ethernet interfaces allowing the safe separation of data traffic from different network segments and the segregation of substation protocol data and test set control commands.
Like other CMC test sets, the CMC 850 is controlled by Omicron’s proven Test Universe software. The new device also offers embedded functions, such as the visualization of received Sampled Values and the calculation of synchrophasors. These functions are easily accessible with a standard Web browser through a Web interface. Existing Test Universe users can benefit from being able to use test plans that they have created for other CMC test units.
The CMC 850 can generate up to three Sampled Values streams. Up to 360 inputs and outputs are available for the simulation and subscription of GOOSE messages. In addition to the Ethernet interfaces the device offers 12 low-level analog outputs for operating test objects with low level inputs or to control external amplifiers. Since time synchronization is often required in IEC 61850 applications, an appropriate IRIG-B converter is supplied with the CMC 850.
