Energy logging is now within your reach? discover where you’re wasting energy, optimize your facility’s energy use and reduce your bill. The three-phase electrical energy logger introduces 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. The purpose of this tool is to make it feasible for a greater variety of licensed electrical professionals to setup and connect the logger, and for a facility manager to review energy usage logs without being a power quality expert. 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.


Key measurements: voltage, current, power, power factor and associated values enable energy
saving strategies to be implemented
Bright, color touch screen: perform convenient in-the-field analysis and data checks with full graphical display
Comprehensive logging: all measured values are automatically logged and can be reviewed during logging and before downloading for on the-go analysis. More than 20 separate logging sessions can be stored on the instrument
Optimized user interface: quick, guided, graphical setup ensures you’re capturing the right data every time, and the intelligent verification function indicates correct connections have been made, reducing user uncertainty
Complete ‘in-the-field’ setup through the front panel: no need to return to the workshop for download and setup or to take a computer to the electrical panel
Fluke Connect Enabled: Connect to up to two FC modules for associated analog values and view live data wirelessly for the Fluke 1734
Wide range power: power instrument directly from the measured circuit eliminating the need to find a power outlet while allowing the instrument to be secured safely inside electrical panels
Two USB ports: one for PC connection and another for fast, simple download to standard USB thumb drives, or other USB devices.
Compact size: designed to fit in tight spaces and panels
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: 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
Security: safeguard against theft with a Kensington lock

How Can The Fluke 1732 and 1734 Work For You

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 220-87 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.
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.

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.

Use up to two Fluke Connect wireless modules with the Fluke 1734 to capture analog measurements.
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 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 energyusage 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.

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.
