The Fluke 1744 Three-Phase Power Quality Logger Memobox with Flexible Current Probes is a compact and rugged everyday instrument for technicians who troubleshoot and analyze power distribution systems. Capable of simultaneously logging up to 500 parameters for up to 85 days and capturing events, the 1744 helps uncover intermittent and hard-to-find power quality issues. The included PQ Log software quickly assesses the quality of power at the service entrance, substation, or the load, according to the latest EN50160 standards.

Plug and Play

The 1744 features easy plug and play setup for immediate use. The current probes are connected to the logger with a single plug. The instrument automatically detects, scales, and powers the probes using line power from the measured voltages. All accessories are individually calibrated and can be shared with multiple Fluke 1740 series loggers. Once it is connected, logging begins with the touch of a single button.

Electrical Shock Protection

This logger features double insulated enclosures and accessories to help prevent electrical shock when coming into contact with blanket bus bars, terminals, or cables. They are also designed to meet the stringent 600V CAT III and 300V CAT IV environmental safety standards.

Measure all Power Quality and Power Parameters

The 1744 logs over 500 different parameters for each averaging period. This allows you to analyze power quality in detail and to correlate intermittent events, helping to identify the root cause of disturbances.

Calculate Current Harmonics

Fluke 1744 logger can calculate the limits of current harmonics to predict overload of the grid according to the standards VSE, VEOE and VDN (among others). This powerful predictive maintenance feature enables current harmonics to be observed before a distortion appears in the voltage.

View Graphs and Generate Reports

With its easy-to-use interface, the included PQ Log software assists you with logger setup, enables you to verify actual measurement values quickly using the online function, and downloads data from the logger to connected PC's (with a standard Windows operating system). You can view the logged data in graphical and tabular form, export it to a spreadsheet, or generate professional reports with the Report Writer function.
