The Fluke 438-II Power Quality Analyzer & Motor Analyzer helps you effectively evaluate electrical and mechanical performance just by hooking up voltage and measuring current, providing you with an unprecedented level of data.
Other useful features:
- Calculates mechanical power and efficiency without mechanical sensors. Just connect to the input conductors
- Measures 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
- Uses PowerWave data capture to capture fast RMS data and show half-cycle averages and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching, etc.)
- Offers waveform capture function to capture 100/120 cycles (50/60 Hz) of each detected event, in all modes, without set-up
- Uses automatic transient mode to capture waveform data at 200 kS/s on all phases simultaneously up to 6 kV
- Automatically calculate motor derating according to NEMA/IEC guidelines
- Fluke Connect® compatible so you can view data locally on the instrument, via Fluke Connect mobile app and PowerLog 430-II desktop software
