1742, 1746 and 1748 Three-Phase
Power Quality Loggers

Troubleshoot, quantify energy usage and perform
quality of service surveys easier than ever

The Fluke 1742, 1746 and 1748 Three-Phase Power Quality
Loggers give you fast, easy access to the data you need to make
critical power quality and energy decisions in real-time.

Compact and rugged, the Fluke 1740 Series Three-Phase Power
Quality Loggers are designed specifically for technicians and
engineers who need the flexibility to troubleshoot, quantify
energy usage and analyze power distribution systems. Fully
compliant with international power quality standards such as
IEC 61000-4-30 and capable of simultaneously logging up to 500
parameters while also capturing events, the Fluke 1740 Series
helps uncover intermittent and hard-to-find power quality issues
more easily than ever. The included Energy Analyze plus software
quickly assesses the quality of power at the service entrance,
substation, or at the load, according to national and international
standards like EN 50160 and IEEE 519.

MEASURE ALL POWER QUALITY AND
POWER PARAMETERS

1748 logs over 500 dif ferent parameters for
each averaging period.

ONE-CLICK REPORTING

Create detailed reports according the
most common power quality standards
in seconds.

EASY TO USE

Auto-configuration check ensures every
measurement campaign is right, the
first time. Power the instrument from the
measured line to simplify the connection
process.

An optimized 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.

potential root causes of power quality issues.

• Measure key power quality parameters:

Measures harmonics and interharmonics for
voltage and current, also includes unbalance,
flicker and rapid voltage changes.

• Optimized user interface: Capture the right

data every time with quick, guided, graphi­cal PC based application setup and reduce
uncertainty about your connections with
an intelligent verification feature and the
only auto-correction function for a power
quality logger. Connection errors are auto­matically indicated via an amber light on the
units power button which turns green once
corrected.

• Flexible power supply: Powers directly from

the measured circuit with the widest available
range for a power quality logger automatically
going from 100 V to 500 V or from a wall line
cord, so you can test anywhere.

• Rugged and reliable: Designed to withstand

harsh installation environments with IP65
rating when used with IP65 voltage input
adapter.

• Two external USB ports: One for PC con-

nection and another for quick, simple data
download to standard USB thumb drives, or
other USB devices, allowing you to leave the
measurement device in place without disrupt­ing logging.

• Ethernet connectivity: Wired and wireless

connections for instrument setup and high­speed data download.

• Compact size: Designed to fit in tight spaces

and panels with small 23cm x 18 cm x 5.4 cm
(9.1 in x 7.1 in x 2.1 in) footprint.

• Highest safety rating in the industry: 600V

CAT IV/1000 V CAT III rated for use at the ser­vice entrance and downstream.

• Optimized measurement accessories: Unique

tangle-free flat voltage cable and thin flexible
current probes ensure easy installation even in
tight spaces.

• Battery life: Four-hour operating time (backup

time) per charge on lithium-ion battery to
withstand temporary power disruptions.

• Security: Safeguard your best asset from theft

with a standard chain or other security device.

• Magnetic hanger kit: Conveniently stow the

instrument safely inside or outside of electri­cal panels; compatible with all models and
included with 1748 model as standard.

Basic PQ Option

Advanced PQ Option Option

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.

Connection verification function shows whether the instr ument is connected correctly

Fluke-Direct

and automatically corrects issues at the press of a button.

The thin current probes are designed to easily
get through tight conductor spacing and include
a wide range (from 1.5 A to 6000 A 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.
