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.
The ideal portable motor analysis test tool, the 438-II can help locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems, while giving technicians the mechanical and electrical information they need to effectively evaluate motor performance.
| Key Features |
| Measure key parameters on direct-on-line motors and motors driven by specific variable frequency drive systems including torque, RPM, mechanical power and motor efficiency |
| Perform dynamic motor analysis by plotting of motor de-rating factor against load according to NEMA 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 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 |
