Product overview: Fluke 1735 Three-Phase Power Quality Logger

Power Quality Logging, Electrical Load Studies and Energy Consumption Testing Made Easy

Fluke’s 1735 Three-Phase power data logger is Fluke's most versatile multi-purpose power quality and energy analyzer on the market for the price and is the ideal power meter for conducting energy studies and basic power quality logging. Set the Power Logger up in seconds with the included flexible current probes and color display. The power quality meter measures most electrical power parameters, harmonics, and captures voltage events.

Most Common Applications:

  • Load studies - verify electrical system capacity before adding loads

  • Energy assessments - quantify energy consumption before and after improvements to justify energy saving devices

  • Harmonics measurements - uncover harmonic issues that can damage or disrupt critical equipment

  • Voltage event capture - monitor for dips and swells that cause spurious resets or nuisance circuit breaker tripping
