Measuring Terminal MT-40

Monitoring control and protection – smart grids

Measuring Terminals of the MT-40 series are designed for measuring, monitoring, recording and analyzing the power quality of power generation, distribution and transmission systems. By quickly sampling the measured current and voltage quantities, the processor calculates the true RMS values of the current, voltage, power, energy, power factor and frequency. In addition to measuring the current electrical quantities, the processor calculates the maximum, mean and minimum values of current, voltage, power in the time interval (MD) and registers the specified quantities.
In accordance with EN 50160 and Class IEC 61000-4-30, class A, MT-40 analyzes the quality of the electrical parameters of the grid (harmonic distortion, harmonic content, surge and voltage drops, voltage flicker, asymmetry etc.) for controlling the realization of contractual relations of sale or purchase of electricity. Graphic color LCD makes the information about the status of a particular part of the grid available locally, and via the embedded Web server they are available remotely. The Measuring Terminal also enables local display of EN 50160 on the device. Reports are also available via e-mail. The four communication lines and software packages MT-DIALOG 3, MT-QUALITY, IPQS or Web browser provide complete remote quality control of the grid.
