Introducing the Class A Fluke 435 with enhanced logging and reporting.

The Fluke 434 and 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

CAT IV 600 V and CAT III 1000 V safety rating:

Designed to help protect you and your equipment, the Fluke 430 Series analyzers 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.

Troubleshoot real-time

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 background recording continues.

Auto Trend AutoTrend automatically records all displayed parameters in the background. Toggle between data and trend view, and use cursors and zoom to analyze measurements without interrupting the recording.

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.

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 voltage and current were defined long ago, many power quality parameters were not previously defined, forcing manufacturers to develop their own algorithms. With so much variation between instruments, electricians tend to waste too much time trying to understand an instrument’s capabilities and measurement algorithms instead of understanding the quality of the power itself!

The new IEC 61000-4-30 Class-A standard takes the guesswork 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 results. In addition, the accuracy, bandwidth and minimum set of parameters are all clearly defined.

Measures everything

Measure true-rms and peak voltage and current, frequency, dips and swells, transients, interruptions, power and power consumption, peak demand, harmonics up to the 50th, interharmonics, 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.

Simple Menu Simple menu structure with logical function grouping gives fast access to key measurements.

Inrush Function Inrush function automatically triggers off of current, and captures start up measurements on motors and other devices to help determine trip levels.

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 microseconds.

A detailed list is given of all events falling outside the set limits. By scrolling through the events list and selecting an event, the event can be analyzed in detail.

System-Monitor: 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.

The System-Monitor overview screen gives instant insight into whether the voltage, harmonics, flicker, frequency and the number of dips and swells fall outside the set limits.

Extensive data analysis possibilities

The Fluke 430 Series provides 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.

Easy-to-use

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 threephase and single-phase configurations guide you through connections.

Scope View Scope view shows voltage and current waveforms for three phase installations. You can toggle to a phasor diagram at any time.

Phasor Diagram Phasor diagram shows voltage and current unbalance, and helps verify connections.

3-Phase Wiring The full color display uses region specific industry standard color-coding (user selectable) to correlate measurements with actual wiring.
