Fluke 1748 Three-Phase Power Quality Logger

Power Quality Logger with 60 cm 1,500A iFlex The Fluke 1748 Power Quality Logger is a compact device for technicians and engineers to troubleshoot, quantify energy usage, and analyse power distribution systems. The Fluke 1748 is compliant with international standards such as IEC 61000-4 -30 and IEC 62586. The 1746 can simultaneously log up to 500 parameters and capture events to find intermittent and hard-to-find power quality issues. The Fluke 1748 logs over 500 different parameters for each averaging period. This allows you to analyze power quality in detail and to correlate intermittent events with detailed waveform data, helping to identify the root cause of disturbances. An optimised user interface, flexible current probes, and an intelligent measurement verification function that allows you to digitally verify and correct connections makes setup easier than ever and reduces measurement uncertainty. Minimize your time in potentially hazardous environments and reduce the hassle of suiting up in PPE by using a wireless connection (WiFi) to view data directly in the field. The included Energy Analyze Plus software enables thorough analysis of the captured data and reporting according to national and international standards such as EN 50160.
