Technical Data
Fluke 1750
Three-Phase Power Recorder
Never miss capturing a
disturbance—with the exclusive
threshold-free measurement
system, it’s automatic.
Capture every measurement, every
event, on every cycle, all the time
with the Fluke 1750 Power Recorder.
Outstanding accuracy and resolution
provide complete visibility into your
installation or distribution system.
Technical Data
• Power quality that meets the standard:
All measurements comply with IEC61000-4-30
standards for correct evaluation of all measured
values including voltage, current, power, harmonics, flicker etc.
• Wireless interface: Included Android tablet
allows for quick setup and verification with
waveform displays, meter screens, and phasor
diagrams.
• Quick and reliable configuration: Android
tablet wireless “front panel interface” provides
the ability to verify setup without a laptop along
with a window into what the instrument is
recording, even in awkward test locations.
• Threshold-free setup: Apply thresholds after
data is collected with Fluke Power Analyze
Software so there is no need to worry about
missed information due to incorrect set-up.
• Captures everything: Cross-channel and cur-
rent triggering capture every measurement, on
every channel, every time.
• Intuitive PC software: Easily analyze data and
generate reports. Automated EN50160 reporting
and compliance.
• Plug and play: Set up in minutes with self-
identifying current probes and single-lead
voltage connections.
• No need to reconnect wires: Swap channels
internally with the wireless front panel or PC
when connections are not correct.
• Measure every parameter: voltage and current
on three phases, neutral, and ground.
• 5 MHz, 8000 Vpk waveform capture: Get a
detailed picture of even the shortest events.
• Quickly retrieve data: With included SD
memory card or via the 100BaseT ethernet
connection.
Easy to use
The recorder automatically
detects, scales, and powers
current probes without needing
batteries or external power supplies. Requiring only single-lead
voltage connections enables safe
and quick setups. Once power is
applied the instrument automatically begins recording and
LEDs give you assurance that
the recorder is powered up and
signals are within range—no
more uncertainty that data is
being recorded. The Fluke 1750
has an exclusive capture algorithm which makes certain all
events are captured without the
tedious setups and blind spots
associated with threshold driven
equipment.
The Android tablet wirelessly
interfaces with the recorder,
Applications
Long-term analysis
Uncover hard-to-find or intermittent issues;
monitor critical equipment, capturing power
quality events to correlate with equipment
malfunction
Power quality surveys
Quantify power quality throughout a facility,
documenting results with professional reports
Quality of service compliance
Validate incoming power quality at the service
entrance
Equipment Installation/Commissioning
Benchmark power system prior to install to
insure quality of service
allowing quick setup and verification with waveform displays,
meter screens, and phasor
diagrams. The built-in wireless
technology allows you to control
multiple instruments from a distance easily, without the need
for a laptop computer (laptops
can also be used when desired).
Configurations are simple with wiring
diagrams to guide you.
View measurements real-time with
wireless tablet interface.
2 Fluke Corporation Fluke 1750 Three-Phase Power Recorder
No need to reconnect wires—swap
channels internally using the tablet
interface.
Comprehensive power system data
Every cycle on every channel is simultaneously
sampled providing complete analysis of power
quality, harmonics, power and energy. Crosschannel current and voltage triggering captures
event data on all input channels simultaneously,
no matter which channel triggered the event.
When periodic analysis of the waveform may be
needed, the Snapshot mode captures waveforms
at user-defined intervals. Even dc signals can be
recorded!
Events can be displayed against a variety of tolerance curves.
Display multiple parameters simultaneously on one graph.
Full FFT on each channel to the 50th harmonic.
Full-featured power meter display for each channel and totals.
Thresholds for the EN50160 report are easily customized.
Powerful data management
Data is automatically stored on the internal flash
memory that can store records for over a month
without compression or overwriting. Data is
retrieved via one of two quick and easy options:
download the data onto the included SD memory
card without using your laptop, or transfer
directly to your computer via Ethernet, using
TCP/IP protocol.
3 Fluke Corporation Fluke 1750 Three-Phase Power Recorder
EN50160 report delivers an easy to read pass or fail chart
along with drill down data.
Voice, data, and picture annotations can be
made via the tablet to flag important points in the
data stream. Imagine being able to flag in your
recorded data when a transfer switch was operated, or load changes were made.
View data the way you want
The new Fluke Power Analyze software revolutionizes your ability to analyze data. No need to
worry about thresholds—with Fluke Power Analyze, thresholds can be modified after the data is
recorded! And the easy-to-use user interface will
display voltage as a phase-to-phase or phase-toneutral reading.
Apply thresholds to data after collection using a variety of
standard or customized templates.
All the latest power quality
standards are built-in
Simplified report writer feature included in
Fluke Power Analyze.
IEC 61000-4-30 compliant measurement systems provide
the confidence that all parameters are measured and calculated consistently with international standards. Automated
EN50160 compliance reporting for rapid Pass/Fail testing.
600 V CAT IV and
1000 V CAT III safety rating
Designed to help protect you and your equipment,
the Fluke 1750 Three-Phase Power Recorder and accessories
are all certified to meet the stringent safety standards for use
in 600 V CAT IV and 1000 V CAT III environments. They are the
first tools of their kind to carry the CAT IV rating and, therefore,
can be used for most power connections and for all outlets in a
low-voltage power distribution system.
4 Fluke Corporation Fluke 1750 Three-Phase Power Recorder
Fluke power quality current
transformers and flexible
current probes are specially
designed to work seamlessly
with Fluke power monitors
(1750 and 1650). All clampon and flexi-CT’s are matched
to take full advantage of your
instrument’s ability to set scale
factors for accurate readings.
