In this video, See how Bob Despres at Jacobs Vehicle Systems® is using the Fluke 438-II Power Quality Analyzer & Motor Analyzer to better understand the performance and efficiency of critical electrical motors to reduce downtime and help achieve his OpEx reduction goals.

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. The Fluke 483-II can measure the following:

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 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.

Some key features include:

• Measure key parameters like speed, torque and mechanical power without mechanical sensor all while the motor is in service simply by using three-phase input measurements

• Calculate Mechanical Power and Efficiency without the need of mechanical sensors

• 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

• 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
