The Fluke 1734 Three Phase Electrical Energy logger delivers easy to use three phase power measurement data for discovering sources of electrical energy waste, overloaded circuits and help you perform routine load studies. Discover when and where energy in your facility is being consumed - from the service entrance to individual circuits. Access and share three phase power data remotely with your team via the Fluke Connect® app so you can maintain safer working distances and make critical decisions in real-time, reducing the need for protective equipment, site visits and check-ins.

Profiling energy usage across your facility helps you identify opportunities for energy savings, and provides you with the data you need to act on them. The new Energy Analyze software package allows you to compare multiple data points over time to build a complete picture of energy usage, which is the first step to reduce the cost of your energy bill.

• Automatically capture and log voltage, current, power, power factor, energy and associated values
• Fluke Connect® compatible, so you can view data locally on the instrument, via Fluke Connect mobile app and desktop software or through your facilities’ WiFi infrastructure
• Power instrument directly from the measured circuit
• The 600 V CAT IV/1000 V CAT III rating (for use at the service entrance and downstream) boosts the highest safety rating in the industry
• Measure all three phases With included 3 flexible current probes
• More than 20 separate logging sessions can be stored on the instruments. In fact, all measured values are automatically logged so you never loose measurement trends. They can even be reviewed during logging sessions and before downloading for real-time analysis
• Optimized user interface
• Quick, guided, graphical setup ensures you’re capturing the right data every time, and the intelligent verification function indicates correct connections have been made, reducing user uncertainty
• Bright, color touch screen allows you to perform convenient in-the-field analysis and data checks with full graphical display
• Capture the right data every time with quick, guided, graphical setup and reduce uncertainty about your connections with the intelligent verification function
• Complete “in-the-field" setup through the front panel or Fluke Connect
• Download and analyze every detail of energy consumption with our automated reporting
