Extech 3-Phase Power & Harmonics Analyzers. Datalog up to 52,428 single-phase readings or 17,476 three-phase readings Flexible clamp probes for wrapping around bus bars and wire bundles. Display of waveform with peak values (1024 samples/period). Maximum demand (MDkW, MW, kVA, MVA) with programmable period. Simultaneous display of harmonics and waveform. Analysis of total harmonic distortion (THD-F). Adjustable CT ratio (1 to 600) and VT ratio (1 to 3000). Graphic phase diagram with 3-phase system parameters. 3-phase voltage or current unbalanced ratio (VUR, VIR) and unbalanced factor (d0%, d2%). Calculated unbalanced current through neutral line (In). Captures 28 transient events (including dip, swell and outage) with programmable threshold (%). Optically isolated USB interface with software to download waveforms, power parameters, and harmonics. Clamp-on True RMS power measurements with on-screen harmonics display. Large backlit LCD displays up to 35 parameters in one screen These power and harmonic analyzers are designed to capture voltage events and harmonics quickly and accurately. Units feature a rugged design making them ideal for challenging industrial environments, and the intuitive user-interface makes set up and operation simple.
