CMC 256plus - Protection Relay Test Set and Universal Calibrator

The CMC 256plus is the right choice if high precision is required. This device is not only an excellent protection test set for all protection generations (from IEC 61850 IEDs to high-burden, electromechanical relays - in single-phase mode) but also a universal calibrator. The CMC 256plus supersedes the well-known CMC 256-6 test set.

The high end hardware design with it’s unrivaled stable signal generation and the extremly low drift enables OMICRON to specify accuracy data that are guaranteed for one year. The high-accuracy current and voltage sources allow the user to calibrate a wide spectrum of measurement devices used in power engineering including electricity meters of class 0.2, transducers, power quality-, and synchrophasor measurement devices (IEEE C37.118). It is unique in that the sources are the reference, thus no additional reference meter is required.
