Measuring Terminal MT-30S

MT-30 series Measuring Terminals are designed for measuring, monitoring, registering and analyzing the electrical power quantities in 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 power value, 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-30 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. Using the graphic LCD, information on the status of a particular part of the grid is available locally. Four communication lines and Quality Control Systems MTPQS or IPQS provide complete remote quality control of the grid.
