EXTECH
PQ3350 POWER QUALITY ANALYZER
Model: PQ3350
Extech PQ3350 Power Quality Analyzer
Details
Use Extech's PQ3350-1 to accurately carry out power
measurements, analysis and datalogging of single, 3-phase, 3-wire and 4 wire
systems.
Once connected up to a system the PQ3350-1 has an
extensive suite of measurement functions which can be displayed as harmonic
analysis, power analysis or phase analysis. The tester can be used to measure
AC voltage levels, AC current, active power (kW), apparent power (kVa),
reactive power (kVAR), power factor, frequency, phase, harmonics, crest factor,
active power energy and reactive power energy (the included flexible current
clamps are used for current measurements).
The PQ3350-1 includes a large amount of functions
designed for specific measurements including simultaneous display of harmonics
and waveform, display of waveform with peak values (1024 samples/period),
analysis of total harmonic distortion and much more.
In order to make sure that results are stored for
later use the PQ3350-1 includes built-in datalogging functions allowing it to
store up to 52428 records for single phase or 17476 records when used on 3
phase systems. This information can be downloaded directly to PC via a USB
connection and interacted with using the included software package.
This tester is available in two variations: this
version, the PQ550-1, comes with 1200A 12" flexible current clamp probes.
The other model, the PQ3350-3, comes with 3000A 24" flexible current clamp
probes. The basic functionality of both testers is the same.
