Fluke 1748/B/EUS Power Quality Logger
The Fluke 1742, 1746 and 1748 Three-Phase Power Quality Loggers give you fast, easy access to the data you need to make critical power quality and energy decisions in real-time. With the included Energy Analyze Plus software package, you can easily create detailed reports.
Hardware Features
- Comprehensive Measurement: Measure all three voltage and current phases plus the neutral current. Includes three-phase and neutral voltage leads and four flexible current probes.
- Comprehensive Logging: Store more than 20 separate logging sessions. A wide range of power and power quality variables are automatically logged so you never lose measurement trends.
- Premium Accuracy: Meets the rigorous IEC 61000-4-30 Class A Edition 3 standard for "Testing and measurement techniques — Power quality measurement methods."
- Advanced Event Capture: The 1748 specifically includes event waveform capture and RMS event profiles, along with date, timestamp, and severity information to pinpoint root causes.
- Key Parameters: Measures harmonics, interharmonics, unbalance, flicker, and rapid voltage changes.
- Optimized User Interface: Quick, guided, graphical PC-based setup ensures you capture the right data. Intelligent verification indicates correct connections, reducing uncertainty. Connection errors are indicated by an amber light that turns green once corrected.
- Flexible Power Supply: Powers directly from the measured circuit (100 V to 500 V) or from a wall line cord.
- Rugged Design: IP65 rating for harsh environments (when used with IP65 voltage input adapter).
- Connectivity: Ethernet (wired and wireless) and two external USB ports for PC connection or data download to thumb drives.
- Compact & Safe: Small 23 cm x 18 cm x 5.4 cm footprint with a 600 V CAT IV/1000 V CAT III safety rating.
- Battery Life: Four-hour backup time per charge on lithium-ion battery.
- Magnetic Hanger Kit: Standard on the 1748 model for safe placement inside or outside electrical panels.
Software Features
- Energy Analyze Plus: Download and analyze every measured detail of energy consumption and power quality state-of-health with automated reporting.
- One-Touch Reporting: Create standardized reports according to EN 50160, IEEE 519, or GOST 33073 standards.
- Advanced Analysis: Create highly customized views of logged measurements for advanced data correlation.
