  • The new 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.

    Motor torque

    Calculates the amount of rotational force (displayed in lb.ft or Nm) developed by a motor and transmitted to a driven mechanical load. The motor torque is the single most critical variable that characterizes the instantaneous mechanical performance of rotating equipment driven by electric motors.

    Motor speed

    Provides the instantaneous motor shaft rotational speed. Combined with the motor torque, motor speed provides a snapshot of the mechanical performance of rotating equipment driven by electric motors.

     

    Motor mechanical load

    Measures the actual mechanical power (displayed in hp or kW) produced by motors and provides a direct link to overloading conditions without simply basing it on the motor current.

    Motor efficiency

    Shows the effectiveness of each motor within a machine, assembly line, plant, and/or facility in converting electric power to useful mechanical work. By properly aggregating the efficiencies of a population of motors the total (aggregate) efficiency can be estimated. Comparisons to expected motor efficiencies at observed operating conditions can help quantify the cost associated with motor energy inefficiency.

    How it works

    Using proprietary algorithms, this power quality and motor analyzer uses three phase current and voltage waveforms to calculate motor torque, speed, load and efficiency at a 1 second update rate. The motor air gap field, as observed via the voltage/current waveforms, provides the basis for the measurements. Mechanical sensors and intrusive no-load motor testing is not required, making it faster than ever to analyze overall electric motor performance.

    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 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 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
    • Supports motor design types NEMA A, B, C, D & E and IEC type H and N
    • Rated torque is calculated from rated power and rated speed
    • Update rate of Motor Measurements is 1x per second
    • Default Trend duration is 1 week
