The Fluke 1742, 1746, and 1748 Three-Phase Power Quality Loggers are robust tools for energy studies, power quality troubleshooting, and load analysis in industrial settings. They log over 500 parameters, including voltage (1000 V, ±0.1%), current (1 A to 6000 A, ±1% to 1.5%), power, harmonics (up to 50th), flicker, unbalance, and events like dips, swells, and inrush, using 16-bit, 10.24 kHz sampling.
Compliant with IEC 61000-4-30 Class A, the 1748 adds waveform snapshots and transient capture, while the 1746 includes basic power quality metrics, and the 1742 focuses on energy logging (upgradable to 1746/1748). Four flexible current probes (1 A to 6000 A) are auto-detected, with intelligent verification and auto-correction for accurate setups. WiFi, Ethernet, and USB enable data downloads, and Energy Analyze Plus software generates EN 50160, IEEE 519, and GOST reports.
Weighing 1 kg, these IP65-rated, CAT IV 600V/CAT III 1000V loggers feature a 4-hour Li-ion battery, operate in -25 °C to 50 °C, and store 20+ sessions. The kit includes voltage leads, alligator clips, flexible probes (non-B models), USB cable, soft case, cable markers, and a magnetic hanger (1748). Optional accessories include longer leads, additional probes, and a GPS receiver. Backed by a two-year warranty, the Fluke 1740 Series delivers precise, reliable power quality diagnostics in harsh environments.
