Fluke 438-II Power Quality and Motor Analyzer

The ideal portable motor analysis test tool to locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems.

 The Fluke 438-II Power Quality and Motor Analyzer adds key mechanical measurement capabilities for electric motors to the advanced power quality analysis functions of the Fluke 430 Series II Power Quality Analyzers. Quickly and easily measure and analyze key electrical and mechanical performance parameters such as power, harmonics, unbalance, motor speed, torque and mechanical power without the need of mechanical sensors. Fluke 434-II, 435-II and 437-II Power Quality Analyzer users can add motor analysis capabilities to their existing units with the Fluke-438-II/MA Motor Analyzer upgrade kit.

 

 

Features:

 

  • Measure key parameters on direct-on-line motors including torque, RPM, mechanical power and motor efficiency

  • Perform dynamic motor analysis by plotting of motor derating factor against load according to NEMA/IEC guidelines

  • Calculate mechanical power and efficiency without the need of mechanical sensors, just connect to the input conductors and you’re ready to go

  • Measure electrical power parameters such as voltage, current, power, apparent power, power factor, harmonic distortion and unbalance to identify characteristics that impact motor efficiency

  • Identify power quality issues such as dips, swells, transients, harmonics and unbalance

  • PowerWave data technology captures fast RMS data, and shows half-cycle averages and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.)

  • Waveform capture function captures 100/120 cycles (50/60 Hz) of each event detected event, in all modes, without set-up

  • Automatic transient mode captures waveform data at 200 kS/s on all phases simultaneously up to 6 kV

  • Fluke Connect® compatible* – view data locally on the instrument, via Fluke Connect mobile app and PowerLog 430-II desktop software

  • Safety rated for industrial applications 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream
