  • Analyze according to NEMA limits—derating information indicates the impact of poor power quality
  • Test motor efficiency, mechanical power, torque, and rpm
  • Measure power quality dips, swells, transients, harmonics, and unbalance
  • Assess voltage, current, power, apparent power, power factor, and unbalance
  • All of this from one instrument and no special sensors needed!
  • Order model 20000-23 to include Fluke Connect® mobile app—transmit results wirelessly to your smart phone or tablet
Avoid downtime from bad motors by adding this portable power quality and motor analyzer as part of a preventative maintenance program. Three-phase electrical measurements include electrical power, unbalance, power factor, and harmonic distortion to help eliminate poor power quality as a source of motor failure. Quickly quantify performance on directly coupled motors relative to their design specification. Calculate power, torque, speed, and efficiency without the hassle of load sensors and obtain real-time load factors under actual operating conditions.
Unique derating factor is determined according to the National Electrical Manufacturers Association (NEMA) standards. Take poor power quality into account and identify motors operating at or beyond their limits—allowing you to make system adjustments to prevent failures, and properly size motors to save on operating costs and downtime.What's included:
Fluke Connect®, four i430 flexible current probes, a test lead set, 8 GB SD card, rechargeable battery and universal power adapter/charger, and soft-sided carrying case.
