Fluke introduces 434/PWR Power Quality Analyser

434PWRJuly 15, 2011Fluke Corporation, the global leader in portable electronic test and measurement technology, has introduced the Fluke® 434/PWR Power Quality Analyser for easy energy analysis.

The instrument helps electricians, field service engineers and maintenance technicians uncover energy waste in commercial and factory buildings as well as in equipment and machines.

The 434/PWR can be used to conduct energy consumption studies and electrical load analysis, and to perform power quality logging and analysis surveys. The power analyser can also help technicians demonstrate the benefits of efficiency improvements by testing energy consumption.

The instrument measures harmonic distortion caused by electronic loads, and analyses reliability problems by capturing voltage dips and swells from load switching.

A full-colour display uses industry-standard, user-selectable colour coding to correlate measurements with actual wiring. It logs incoming data with a unique AutoTrend function that highlights changes of data over time. The data can then be analysed with Fluke’s Power Log software, which is included with the 434/PWR.

AutoTrend gives quick insight into changes over time. With a single push of a button, the system monitor gives an overview of power system performance. It also checks that incoming power complies with standard limits or custom specifications. Trend analysis is made easier by automatic scaling of the vertical axis, so the waveforms can always be shown on a full display.

Load studies and energy assessments
The 434/PWR is a complete three-phase troubleshooting tool that measures virtually every power system parameter: voltage, current, frequency, power, energy consumption, cos ? or power factor, unbalance and harmonics and inter-harmonics.

The instrument captures events like dips and swells, interruptions and rapid voltage changes based upon ½ cycle rms values. Two groups of four channels simultaneously measure voltage and current on all three phases and neutral. The 434/PWR meets 600 V CAT IV, 1000 V CAT III safety standards required for measurements at service entrance.

A logging function lets users customise measurement selections and provides analysis to find intermittent problems or relate power quality issues to other phenomena/events. The logger provides detailed and user-configurable long-term recording. It gives MIN, MAX and AVG readings of up to 100 parameters on all four phases. Averaging time can be selected down to 0.5 seconds (or 1 minute for one day’s recording, 10 minutes for one week, 30 minutes for one month or more).

Extensive data analysis
The 434/PWR can perform extensive data analysis. Cursors and zoom can be used “live” while taking the measurements, or ‘offline’ on stored measurement data. The stored measurements can also be transferred to Power Log software.

Designed to quickly view recorded data, the built-in Power Log software displays all recorded parameters on interactive trends. Users can generate professional-looking, customised reports using the report generator, or copy and paste images into reports manually.
