Fluke 1740 Specifications
Fluke 1740 Series
Three-Phase Power Quality Loggers Memobox
Assess power quality and conduct
long-term studies with ease
Compact and rugged, the Fluke 1740 Series three-phase power
quality loggers are everyday instruments for technicians who
troubleshoot and analyze power distribution systems. Capable
of simultaneously logging up to 500 parameters for up to 85
days and capturing events, the Fluke 1740 Series helps uncover
intermittent and hard-to-find power quality issues. The included
PQ Log software quickly assesses the quality of power at the
service entrance, substation, or at the load, according to the
latest EN50160 standard.

Applications
Disturbance analysis — Uncover root cause of
equipment malfunction for later mitigation and
predictive maintenance
Quality of service compliance — Validate
incoming power quality at the service entrance
Power quality studies — Assess baseline power
quality to validate compatibility with critical
systems, before installation
Load studies — Verify electrical system capacity
before adding loads
Energy and power quality assessment —
Validate performance of facility improvements
by quantifying energy consumption, power factor,
and general power quality, before and after,
improvements
Plug and play
All three 1740 Series loggers feature easy plug and
play setup, for immediate use. The current probes
are connected to the logger with a single plug. The
instrument automatically detects, scales, and pow
ers the probes using line power from the measured
voltages. All accessories are individually calibrated
and can be shared with multiple Fluke 1740 series
loggers. Once it is connected, logging begins with
the touch of a single button!
Electrical shock protection
The Fluke 1740 loggers feature double insulated
enclosures and accessories to help prevent electrical
shock when coming into contact with blanket bus
bars, terminals, or cables. They are also designed to
meet the stringent safety standards for use in 600 V
CAT III and 300 V CAT IV environments.
Loggers for every application
The portable Fluke 1740 Series power quality loggers are designed for easy installation and use, anywhere in low- and medium-voltage applications. There are three
models to choose from to meet your basic or advanced power logging needs:
Fluke 1743: IP65 water-proof model for logging the most common power parameters including V, A, W, VA, VAR, PF, energy, flicker, voltage events, and THD.
Fluke 1744: Includes the same features as the Fluke 1743. In addition to common
power parameters, the Fluke 1744 also measures voltage and current harmonics,
interharmonics, mains signaling, unbalance, and frequency.
Fluke 1745: Advanced IP50 power quality logger with the same measurement
capability as the 1744, plus real-time LCD and five hour UPS.

Measure all power quality and power
parameters
The Fluke 1745 and Fluke 1744 log over 500
different parameters for each averaging period. This
allows you to analyze power quality in detail and
to correlate intermittent events, helping to identify
the root cause of disturbances. For basic power
logging, the Fluke 1743 captures all relevant power
parameters.
Calculates current harmonics
Fluke 1745 and Fluke 1744 loggers can calculate
the limits of current harmonics to predict overload
of the grid according to the standards VSE, VEOE,
VDN, among others. This powerful predictive main
tenance feature enables current harmonics to be
observed before a distortion appears in the voltage.

Statistical summaries like EN50160 and DISDIP table provide a quick,
comprehensive summary. The EN50160 overview display provides a simple
display of 8 power quality parameters on one dashboard, according to the latest
international power quality standard.

For root cause analysis, different measurements such as
flicker, voltage and THD can be shown in the same time
plot, helping to quickly identify the cause of a disturbance.
Statistical analysis of Voltage and Current harmonics over a
given time period. Red bar graphs indicate issues with the
grid. Other colors are warnings for pontential future issues.
Harmonics can be presented also as time plots.
