Measuring Terminal MT-50

MT-50 series Measuring Terminal are designed for measuring, monitoring, registering and analyzing energy quality levels in the most complex systems of power generation, distribution and transmission. 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 power values, 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 Euro stabdard EN 50160 and IEC 61000-4-30 class A, Ed.2 and Ed.3, MT-50 analyzes the quality of the electrical parameters of the grid (harmonic distortion, harmonic content, surge and voltage drop, voltage flicker, asymmetry etc.) in order to control the realization of contractual relations of sale or purchase of electric power. With a large color graphic LCD (5.7 “), information on the status of a particular part of the grid is available locally, and via the embedded Web server information is available remotely. The Measuring Terminal also enables local display of EN 50160. The reports are also available via e-mail. Four communication lines, a range of digital / analog inputs / outputs and MT-DIALOG 3, MT-QUALITY, PQ VISION or Web browsers enable complete grid quality remote control.
