Overview

  • Power Measurements and Analysis with graphical readout
  • Datalogging of single and 3-phase/3-wire or 3-phase/4-wire systems
  • Logs up to 30,000 reading on a removable SD memory card
  • Saves data on an SD card in Excel format

Essential Info

The Extech PQ3470 3-Phase Graphical Power Analyzer’s Large backlighting LCD displays up to 35 parameters in one screen. Logs up to 30,000 reading on a removable SD memory card in Microsoft Excel® format and easily transfers data to a PC for analysis. Expand the current measurement capabilities by adding optional clamp probes available in the following sizes 200A Current Clamp Probes, 1200A Current Clamp Probes or the 3000A Current Flexible Clamp Probes, each sold separately.

The PQ3470 features full system analysis of up to 35 parameters including: V (phase-to-phase), V (phase-to-ground), A (phase-to-ground), KW / KVA / KVAR / PF (phase), KW / KVA / KVAR / PF (system), KWH / KVAH / KVARH / PFH (system), and Phase angle. Additional features include Adjustable Current Transformer CT (1 to 600) and Potential Transformer PT (1 to 1000) ratio for high power distribution systems, a wide sampling rate from 2 seconds to 2 hours, a built-in Clock and Calendar, and an easy-to-use on-screen menu. It also features large, dot-matrix, sun-readable, graphical LCD. Includes on-screen Harmonics display (1 to 50th order), simultaneous display of Harmonics and Waveform, display of Waveform with peak values, analysis of Total Harmonic Distortion (THD), Graphic Phase diagram with 3-Phase system parameters, 3-phase Voltage or Current Unbalanced Ratio (VUR, AUR) and unbalanced factor. You can also capture Transient events (including dip, swell, and outage) with programmable threshold (%).
