Power Quality Analysis


MI 2392 PowerQPlus The MI 2392 PowerQPlus


is a portable multifunction instrument for measurement and analysis of three-phase power sys- tems. Due to the small dimensions and user friendly interface of the MI 2392 PowerQPlus


it is ideally suited for routine or


complex power quality assessment, while a rugged case allows to use it in heavy duty industrial environments. Pre-set measuring profiles allow on-site evaluation of all major power quality parameters (U, I, P, Q, S, PF, cos ϕ, THD, individual harmonic components, etc.) even without using a PC. Built-in memory module ensures up to five days of recording. New powerful PC Software package PowerView comes delivered as part of a standard set and enables downloading, complex analysing and comparison of recorded data and creation of test reports.


MEASURING FUNCTIONS:


• TRMS voltage; • TRMS current; • Power (active, reactive, apparent); • Power factor, cos ϕ; • Energy (active, reactive, generated, consumed);


• Power quality analysis according to EN 50160;


• Harmonic analysis up to 50th ics, THD measurement;


harmon-


• Capturing and recording of power sup- ply events (shut-down’s, interruptions, swells, dips);
