Fluke introduces the 434/PWR power analyser to make energy analysis easy

Fluke, the global leader in handheld electronic test and measurement equipment, has introduced the Fluke 434/PWR Power Analyser for easy energy analysis. The instrument can uncover energy waste in commercial and factory buildings as well as in equipment and machines.

Fluke introduces the 434/PWR power analyser to make energy analysis easy

The unit is ideal for electricians, field service engineers and maintenance technicians.

It can be used to conduct energy consumption studies and electrical load analysis, and to perform power quality logging and analysis according to EN 50160. The power analyser can also demonstrate the benefits of efficiency improvements by making energy consumption tests.

The new Fluke 434/PWR 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 colour-coding (user selectable) to correlate measurements with actual wiring. It can log incoming data, with a unique AutoTrend function highlighting changes of data over time, and comes with Fluke’s Power Log analysis software.

The Fluke 434/PWR is a complete three-phase troubleshooting tool that measures virtually every power system parameter: voltage, current, frequency, power, energy consumption, cos φ 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 the stringent 600V CAT IV, 1000V CAT III safety standard required for measurements at the service entrance.

A logging function allows users to customise measurement selections and provides analysis of user-selectable parameters 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 1 day’s recording, 10 minutes for 1 week, 30 minutes for 1 month or more).

AutoTrend gives fast 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 to EN50160 limits or to 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.

The Fluke 434/PWR Power Analyser 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 a profes-sional looking report with the ‘PRINT’ function or copy and paste images into report documents manually. The report generator can be customised to easily create tailored formats.
