Applications
Detailed disturbance analysis — Perform high-
speed transient analysis and uncover the root cause
of equipment malfunction for later mitigation and
predictive maintenance. The fast transient option,
with its 6000 V measurement range, allows capture
of very short impulses, such as lightning strikes.
Class-A quality-of-service compliance — Validate
incoming power quality at the service entrance.
With Class-A compliance, the Fluke 1760 allows
undisputable verification.
Event correlation at multiple locations —
Utilizing GPS time synchronization, users can
quickly detect where a fault occurred first, either
inside or outside the facility.
Simultaneous measurement of independent
power systems — Built with Galvanic separation
and dc coupling of voltage inputs, the instrument
can conduct complete measurements on dissimilar
power systems. For example, the Fluke 1760 can
troubleshoot UPS systems by simultaneously record-
ing the battery voltage and power output.
Power quality and power load studies — Assess
baseline power quality to validate compatibility
with critical systems before installation, and verify
electrical system capacity before adding loads.
Fully Class-A compliant
The Fluke 1760 is fully compliant with the new
IEC 61000-4-30 Class-A standard, which defines
the measurement methods required for each power
parameter in order to obtain reliable, repeatable,
and comparable results. With the GPS time
synchronization accessory, data recorded with
multiple instruments can be correlated with
Class-A precision.
Individual trigger settings provide flexibility
when capturing events, rms values, wave-
forms, and fast transients. The instrument
runs with default settings, so that the user
does not need to set triggers in standard
applications. Individual settings can be
stored for next time.
What is Class-A conformity?
Power quality measurement is a relatively new, and quickly
evolving field. There are hundreds of manufacturers around the
world with unique measurement methodologies. Whereas basic
single- and three-phase electrical measurements, like rms volt-
age and current were defined long ago, many power quality
parameters were not previously defined, forcing manufactur-
ers to develop their own algorithms. With so much variation
between instruments, electricians tend to waste too much time
trying to under-stand an instrument’s capabilities and measure-
ment algorithms instead of understanding the quality of the
power itself!
The new IEC 61000-4-30 Class-A standard takes the guess-
work out of selecting a power quality instrument. The standard
IEC 61000-4-30 defines the measurement methods for each
parameter to obtain reliable, repeatable, and comparable re-
sults. In addition, the accuracy, bandwidth, and minimum set
of parameters are all clearly defined.

User-configurable operation
The versatile measurement algorithms and trigger
settings allow the expert and general users to opti-
mize the Fluke 1760 for each application in order
to capture exactly the data required. Data can be
transferred to a computer directly, or via an Ethernet
network and can be retrieved during recording
without interrupting the measurements.
Rugged and reliable
The instrument, accessories, and power supply help
you safely conduct tests with a 600 V CAT IV rating
per EN 61010-1 conformity requirements. The Fluke
1760 features a double insulated enclosure, which
helps protect the user, equipment, and surroundings
from electrical shock. With a 2 GB compact flash
memory instead of a hard disk, there are no rotating
parts inside the instrument, increasing its reliability
and durability for everyday use.
Broad measurement range
Developed in cooperation with power utilities, the
EN50160 statistical analysis presents a summary
of the quality of voltage against internationally
defined limits. When a threshold is exceeded, the
Fluke 1760 automatically captures voltage and cur-
rent waveform data on all phases simultaneously.
Nearly every power quality and power parameter
is measured, including rms values, flicker, voltage
dips, voltage swells, voltage unbalance, current and
voltage harmonics to the 50th, interharmonics, THD,
mains signaling, reactive power, transients, and
power factor.
Plug and play
The Fluke 1760 Power Quality Recorder features
easy plug and play setup for immediate use. The
current and voltage probes are plugged in sepa-
rately to the instrument, which automatically
detects, configures, and provides power to the
probes. All accessories are individually calibrated
and can be shared with multiple Fluke 1760
recorders.

the user to define custom limits
and settings for specific applica-
tions and local standards.

The 1760 provides flagging of data according to IEC 61000-4-30 Class-A. The flagging feature
alerts the user that a dip, swell, or interruption occurred during a specific time interval. Values out
of nominal ranges are marked by either a colored background or with a flag symbol.
By double-clicking on an event, the software displays any
trends and waveforms related to this event.
Using an Ethernet connection, the power can be monitored
in real-time to view phasor diagrams, trends, waveforms,
meter screens and more.
The report-generator function allows
the user to create custom profes-
sional reports quickly and easily.
The PQ Analyze Software features
templates for standard reports.
The event list summarizes how often
an event occurred during the selected
time period.
PQ Analyze Software
The Fluke 1760 includes
comprehensive software for
detailed power quality analy-
sis on Windows® based PCs. In
the online mode, the software
enables remote instrument setup,
job processing, real-time veri-
fication of actual measurement
values, and data download. Data
can be viewed in trend diagrams
for root cause analysis or in a
variety of statistical summaries.
You can also generate profes-
sional reports with the Report
Writer function.

The filters achieve extremely high accuracy throughout a wide frequency range. The
filters protect against voltage transients and, limit the signal rise rate, reduce high
frequency components and especially the noise voltage above half the sampling rate of
the A/D converter by 80 dB. This is also valid under extreme operating conditions such
as transient voltages at the output of converters.
