The Fluke 434 and Fluke 435 three-phase power
quality analyzers help you locate, predict, prevent and troubleshoot problems in
three- and single-phase power distribution systems. Troubleshooting is faster
with on-screen display of trends and captured events, even while background
recording continues. The new IEC standards for flicker, harmonics and power
quality are built right in to take the guess work out of power quality.
IV 600 V and CAT III 1000 V safety rating
Designed to help protect you and your equip-ment, the Fluke 434 and the Fluke
and accessories are all certified to meet the stringent standards for use in CAT
IV 600 V and CAT III 1000 V environments. They are the first tools of their kind
to carry the CAT IV rating for use in power connections and outlets throughout a
low-voltage power distribution system.
AutoTrend feature provides fast insight into changes over time. Every displayed
reading is automatically recorded without having to set thresholds or intervals.
Analyze the trends using the cursors and zoom tools—even while back-ground
Fully Class-A compliant
The Fluke 435 is fully compliant with the new IEC 61000-4-30 Class-A
standard. With this powerful capability, all measurements will be consistent and
reliable in accordance with the latest international standard.
Measure true-rms and peak voltage and cur-rent, frequency, dips and swells,
transients, interruptions, power and power consumption, peak demand, harmonics
up to the 50th, inter-harmonics, flicker, mains signaling, inrush and unbalance.
Logger: record the detail you need
User-configurable, long-term recording of MIN, MAX and AVG readings for up to
100 parameters on all 4 phases. Enough memory is available to record 400
parameters for up to a month with 10 minute resolution, or capture smaller
variations with resolution down to 0.5 seconds.
Automatic transient display
Every time an event or voltage distortion is detected, the instrument triggers
and automatically stores voltage and current waveforms on all three phases and
neutral. The analyzer will also trigger when a certain current level is
exceeded. Up to 40 dips, swells, interruptions and transients can be captured
this way. You can see voltage transients as high as 6 kV and as fast as 5
Summary screen of overall power quality health A single push of the MONITOR
button delivers a dashboard display of rms voltage, harmonics, flicker,
interruptions, rapid voltage changes, swells, unbalance, frequency and mains
signaling. The dashboard is updated live, showing compliance of each parameter
to EN50160 limits or your own limits. Color-coded bars clearly show which
parameters are inside (pass) or outside limits (fail). During a monitor session,
you can easily drill down to more detail of any parameter to view and capture
its trend for a report.
Extensive data analysis possibilities
The Fluke 433, Fluke 434 and Fluke 435 provide three
ways to analyze measurements. Cursors and zoom tools can be used 'live' while
taking measurements, or 'off line' on stored measurement data. Additionally, the
stored measurements can be transferred to a PC with the included software to
perform custom analysis and create reports. Measurement data can also be
exported to common spreadsheet programs. Store up to 10 measurement datasets and up to 50 screen captures for
use in reports.
Pre-programmed setups and user-friendly screens make power quality testing as
simple as you would expect from Fluke. The high-resolution color screen updates
every 200 mS and displays waveforms and wiring diagrams color coded to industry
standards. Handy on-screen wiring diagrams for all commonly used three-phase and
single-phase configurations guide you through connections.
