Fluke has introduced the new Fluke 438-II power quality and motor analyser, adding key mechanical measurement capabilities for electric motors to the advanced power quality analysis functions of the Fluke 430 Series II power quality analysers. They measure and analyse key electrical and mechanical performance parameters such as power, harmonics, unbalance, motor speed, torque and mechanical power without the need for mechanical sensors. The 438-II is the ideal portable motor analysis test tool. It locates, predicts, prevents and troubleshoots power quality problems in three-phase and single-phase power distribution systems, while giving technicians the mechanical and electrical information needed to effectively evaluate motor performance.
The analyser can measure key parameters on direct-on-line motors such as torque, RPM, mechanical power and motor efficiency; perform dynamic motor analysis by plotting motor de-rating factor against load according to NEMA guidelines; and calculate mechanical power and efficiency without the need for mechanical sensors. It also measures electrical power parameters such as voltage, current, power, apparent power, power factor, harmonic distortion and unbalance to identify characteristics that impact motor efficiency and identifies power quality issues such as dips, swells, transients, harmonics and unbalance.
In addition, the PowerWave data technology captures fast RMS data and shows half-cycle averages and waveforms to characterise electrical system dynamics such as generator start-ups and UPS switching. The Waveform capture function captures 100/120 cycles (50/60 Hz) of each event detected event in all modes without set-up, while automatic transient mode captures waveform data at 200 kS/s on all phases simultaneously up to 6 kV.
