Measure all power quality and power parameters—Upgrades available

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.

For basic power quality logging, the Fluke 1746 captures all relevant power parameters for performing energy saving studies and electrical network planning with a full upgrade option to 1748 available. For simple load and energy studies the Fluke 1742 offers optimal performance in a rugged package and can be upgraded to 1746 or complete 1748 functionality.

Calculates current harmonics limits

When downloading data from the Fluke 1748 Power Quality Loggers, Energy Analyze Plus, can calculate the limits of current harmonics based on installation parameters to predict overload of the grid according to a wide range of international standards. This powerful predictive maintenance feature enables current harmonics to be observed before distortion appears in the voltage allowing you to prevent unexpected failures or non-compliance situations and increase system uptime.

Easy to use

Fluke power quality loggers are designed with the technician in mind. The four current probes are each connected separately allowing flexibility and simplicity, the instrument automatically detects, scales and powers the probes so you don’t have to worry about ensuring the measurements are correct.

The thin current probes are designed to easily get through tight conductor spacing and include a wide range (from 1.5A to 6000A depending on selected probe) for high accuracy in each application. An innovative tangle-free, flat, voltage lead makes connection simple and reliable. The instrument’s intelligent ‘Verify Connection’ feature which can be accessed using the PC Setup application automatically checks to make sure the instrument is connected correctly and can digitally correct connections without having to disconnect measurement leads. In the event of a connection error, the power button on the unit will turn from green to amber indicating that the connections should be verified before proceeding.

The loggers can also be conveniently and safely powered directly from the measured circuit (up to 500 V)—no more searching for power outlets or having to run multiple extension cords to the logging location, which is especially useful when logging at a remote site and when installing inside electrical panels.

Analysis and reporting

Capturing logged data is just one part of the task. Once you have the data, you need to create useful information and reports that can be easily shared and understood by your organization or customers. Fluke Energy Analyze plus software makes that task as simple as possible. With powerful analysis tools and the ability to create customized reports in minutes you’ll be able to communicate your findings and quickly solve problems so you can optimize system reliability and savings. A range of built-in report templates for industry standards such as EN 50160, IEEE 519 and GOST enable one-click reporting so you can create high quality reports at the touch of a button. Reports can be modified as standards evolve, or new versions become available.

The flexible data views quickly show details of the measurement file in easy to understand formats. The calendar view shown above enables hour/hour, day/day and week/week comparisons simply by selecting the thumbnail views required. Each selected thumbnail is automatically detailed in the lower window.

Advanced data communication and software:

  • View real-time measurements wirelessly from outside the panel or from your office using the included Fluke Energy Analyze plus software
  • Download logged files directly to a USB flash drive that plugs directly into the USB port of the instrument or by wired or WiFi connection to your PC
  • The export function of Energy Analyze plus enables export of one or more logged values with a simple parameter selector

Rugged and reliable

The 1740 series products are built to withstand tough working environments. The flexible current probes are IP65 rated and suitable for most installation situations; the optional IP65 voltage adapter ensures safe, reliable operation even in harsh conditions.

Standard 2 m leads simplify connection on difficult to access conductors, and optional 5 m leads are useful when installing in difficult locations. With the capability of powering the instruments from the power line up to 500 V, installation is as simple as can be.

Thoughtful design

Fluke prides itself on thoughtful design that’s why 1740 series power quality loggers include simple but effective accessories like the MA-C8 adapter making powering the instrument with a line cord easy when not in the field. Ports that aren’t always needed in the field are IP65 protected including the Ethernet, USB, AUX and I/O ports protecting for both moisture and dirt ingress. The status LEDs give a quick and clear indication of what the instrument is doing without having to touch any controls. Its compact size means that in most cases it will fit into the available space without any problems.
