Fluke 1732 and 1734
Three-Phase Electrical
Energy Loggers
Energy logging is now within your reach—discover
where you’re wasting energy, optimize your
facility’s energy use and reduce your bill
The new Fluke 1732 and 1734 Three-Phase Electrical Energy
loggers introduce a new simplicity to discovering sources of
electrical energy waste. Discover when and where energy in your
facility is being consumed; from the service entrance to individual
circuits. Access and share data remotely with your team via the
Fluke Connect
and make critical decisions in real-time, reducing the need for
protective equipment, site visits and check-ins.
Profiling energy usage across your facility helps you identify
opportunities for energy savings, and provides you with the data
you need to act on them. The new Energy Analyze software package allows you to compare multiple data points over time to build a
complete picture of energy usage, which is the first step to reduce
the cost of your energy bill.

sessions can be stored on the instruments. In fact, all measured
values are automatically logged so you never loose measurement
trends. They can even be reviewed during logging sessions and
before downloading for real-time analysis.

ensures you’re capturing the right data every time, and the
intelligent verification function indicates correct connections
have been made, reducing user uncertainty.

or Fluke Connect: No need to return to the workshop
for download and setup or to take a computer to the
electrical panel.
• Fully integrated logging: Connect other Fluke Connect devices
to the Fluke 1734 to simultaneously log up to two other measurement parameters, virtually any parameter available on a
Fluke Connect wireless digital multimeter or module.*

Applications
Load studies: Discover how much energy
individual pieces of equipment are consuming
when they are operating at minimum and
maximum capacity. Check capacity of circuits
prior to adding additional loads (various standards
exist for this process; in the US the NEC 22087 is the recommended standard). Load studies
can also identify situations where you may be
exceeding the allowable load on the circuit or
when an agreed peak demand applies from the
utility. For convenience, some load studies simply
measure current which makes installation of the
measuring equipment quick and easy. It is often
recommended that load surveys be performed
for 30 days so that all typical load conditions are
encountered during the test.
Energy assessments: quantify energy consumption before, and after improvements, to justify
energy saving devices
Energy surveys: Users often ask where measurements should be taken for an energy survey. The
answer is multiple points within the facility. Start
at the main service feeders; compare the power
and energy measured here with the readings
from the utility meter to ensure you’re receiving
the correct charges. Then move downstream to
the larger loads; these should be easy to identify by the current rating of the electrical panels
downstream of the service entrances. Measuring
at many points will allow a full picture of energy
usage across the facility to be developed. The
next question users typically have is how long an
energy survey should last. This of course depends
on the facility, but it is recommended that you
measure for a period that matches a typical facility activity period. If the facility operates over
a five day work week with down time on the
weekend, a seven day survey will most likely
capture typical conditions. If the facility operates

Suitable for NEC 220 load st udies
at a constant level for 24 hours a day, 365 days a
year, a single day could be reasonably representative as long as you avoid a period where there
may be planned maintenance.
To capture a full picture of the facilities energy
usage it is not necessarily required to have
measurements made simultaneously at every
consumption point in the facility. To get a comprehensive picture, spot measurements can be
made and then compared on a sliding time timescale. For example, you could compare the service
entrance results from a typical Tuesday between
6:00 am and 12:00 pm with those of a larger load
in the facility. Typically there will be some correlation between these profiles.
Logging related analog measurements: When
conducting energy studies, it is useful to log
related analog measurements such as temperature, voltage, current or pressure. These variables
provide a better overall picture of operating
conditions and allow you to correlate asset
performance data with energy consumption.
Correlating these variables provides more of the
data you need to make cost saving performance
adjustments. With the Fluke 1734, up to two
Fluke Connect wireless modules can be used to
capture these measurements, and the values will
be automatically logged along with power and
energy readings.

Applications (continued)
Power and energy logging: When a piece of
equipment is operated it instantaneously consumes a specific amount of power in watts (W) or
kilowatts (kW). This power is accumulated over
the operating time and expressed as energy consumed in kilowatt hours (kWh). Energy is what
your electric utility charges for; there will be a
standard charge from the utility per kilowatt hour.
Utilities may have other additional charges, such
as peak demand, which is the maximum power
demand over a defined period of time, often 15 or
30 minutes.
There may also be power factor charges, which
are based on the effects of the inductive or
capacitive loads in the facility. Optimizing peak
demand and power factor often results in lower
monthly electricity bills. The 1733 and Fluke
1734 Three Phase Electrical Energy loggers have
the capability to measure and characterize these
effects enabling you to analyze the results and
save money.
Simplified load studies: For situations where
it’s either difficult or impractical to make a voltage connection the simple load study feature
allows users to perform a simplified load study by
measuring current only. The user can enter the
nominal expected voltage to create a simulated
power study. For accurate power and energy
studies it is required to monitor both voltage and
current but this simplified method is useful in
certain circumstances.
Log the most common parameters
Designed to measure the most critical threephase power parameters, the 1732 and 1734
can simultaneously log rms voltage, rms current, voltage, voltage and current THD, active
power, reactive power, power factor, active
energy, reactive energy, and more. With enough
memory for more than a year of data logging,
the 1732 and 1734 can discover which loads
are can be optimized to enable you to reduce
your energy bill.
Easy to use
The four current probes are connected separately;
the instrument automatically detects and scales
the probes. The thin current probes are designed
to easily get through tight conductor spacing
and are easily set to 150 or 1500 A for high
accuracy in nearly any application. An innovative
tangle-free flat voltage lead makes connection
simple and reliable and the instrument’s intelligent ‘Verify Connection’ feature automatically
checks to make sure the instrument is connected
correctly and can digitally correct common
connection issues without having to disconnect
measurement leads.
The detachable power supply can be conveniently
and safely powered directly from the measured
circuit—no more searching for power outlets or
having to run multiple extension cords to the
logging location.
Intelligent verification function that digitally corrects most
common measurement connections
Data downloading couldn’t be easier or
more flexible:
• Download directly to a USB flash drive
that plugs directly into the USB port of the
instrument
• View measurements remotely via the Fluke

helping you maintain safer working distances
and reducing the need for personal protective
equipment and unnecessary site visits and
check-ins*
• Integrate energy measurement data along with
other plant maintenance data all in one place.
