HT Italia HT9020

Professional clamp-on power quality analyzer with DYNAMIC INRUSH™
Clamp-on power quality analyzer HT9020 has been designed for measuring DC, AC+DC TRMS current up to 1000A according to CAT IV 600V in compliance with standard IEC/EN61010-1
HT9020 carries out measurements of Active, Reactive and Apparent Power and Energy, voltage and current harmonic analysis up to the 25th order with THD% calculation, in single-phase or three-phase balanced systems. It also tests phase sequence and phase conformity by 1-lead measuring method as well as detects any event related to electric motor starting currents (DYNAMIC INRUSH).  DYNAMIC INRUSH™ permits to measure inrush currents with user-defined time frames, providing measurements more reliable than standard fixed time-frame testers. The user has the chance to recall and display the measurement by applying different time frames. For example, if the user carries out a measurement using a time frame of 100 ms, he can post-process the same measurement by applying a time frame of: 16,7, 20, 50, 100, 150, or 200 ms. This grants the utmost flexibility for each measurement, and prevents to measure again and again to get the real inrush current value. HT9020 is provided with traceable calibration certificate.
