Series MT144 - Advanced three-phase analyser

The MT144 is an advanced measurement device which measures, calculates and displays the primary electrical parameters in balanced or unbalanced three-phase industrial networks



  • Control switchboards for low and medium voltage applications
  • Alarm center by means of voltage-free digital inputs
  • Submetering: can measure through impulses other types of consumption, such as gas, water, steam, etc. via their digital inputs
  • Measurement converters: possible to associate instantaneous parameter to one of the analogue outputs (0 to 20mA / 4 to 20mA)
  • Recording of instantaneous, maximum, and minimum parameters with a date and hour by means of an expandable memory card
  • Power quality analyser: harmonic decomposition up to order 50º, asymmetries, flicker, unbalances, overvoltages, gaps, interruptions, etc.
