HT Italia HT9020 Clamp Meter with Powers/Harmonics and Inrush Currents

Mike — Wed, 24 Aug 2016 03:07:23 +0000

HT9020 Clamp Meter with Powers/Harmonics and Inrush Currents 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.
