Fluke 1730

Three-Phase Electrical

Energy Logger

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 1730 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. 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.

Technical Data

• Key measurements: voltage, current, power,
power factor and associated values enable
energy saving strategies to be implemented.

• Bright, color touch screen: perform conve-
nient 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 on­the-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.

• 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.

• All new, Energy Analyze application soft-
ware: download, analyze and automated

reporting for a complete picture of energy
saving potential.

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 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.

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 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.

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
1730 Three Phase Electrical Energy logger has
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.
