Product Overview: Fluke 1742, 1746 and 1748 Online Removable Power Quality Recorders
The Fluke 1742, 1746, and 1748 in-line removable power quality recorders provide easy and fast real-time access to the data you need to make important power quality and energy decisions.
The Fluke 1740 Series of online, removable power quality recorders are compact, rugged, and designed for technicians and engineers who need the flexibility to troubleshoot, quantify energy usage, and analyze power distribution systems. With the ability to record up to 500 parameters simultaneously and capture events, it's easier than ever to identify intermittent or hard-to-find power quality problems. The included Energy Analyze Plus software quickly evaluates power quality at the feeder, substation, or load in accordance with national and international standards such as EN 50160 and IEEE 519.
With an optimized user interface, flexible current probe, and smart measurement verification features, you can digitally verify and correct connection errors, making setup easier than ever and reducing measurement uncertainty. Use wireless connectivity (WiFi) to view data directly in the field, minimizing your time spent in potentially hazardous environments and reducing the need to wear personal protective equipment.
The Fluke 1748 can record more than 500 different parameters during each averaging period. This allows you to analyze power quality in detail and correlate events with detailed waveform data to help determine the root cause of disturbances. For basic power quality logging, the Fluke 1746 captures all relevant power parameters for energy conservation studies and grid planning, with an option to upgrade to the 1748. For simple load and energy studies, the Fluke 1742 provides excellent performance in a ruggedized package and can be upgraded to 1746 capability or full 1748 capability.
