Fluke 434/PWR power quality analyser

The Fluke 434/PWR power quality analyser is designed to help electricians, field service engineers and maintenance technicians uncover energy waste in commercial and factory buildings as well as in equipment and machines. It can be used to conduct energy consumption studies and electrical load analysis, and to perform power quality logging and analysis surveys.

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 its AutoTrend function that highlights changes of data over time. The data can then be analysed with Fluke’s Power Log software, which is included.

The 434/PWR is a complete three-phase troubleshooting tool that measures virtually every power system parameter: voltage, current, frequency, power, energy consumption, power factor, unbalance, harmonics and interharmonics.

The instrument captures events like dips and swells, interruptions and rapid voltage changes based on 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.

The logger function 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 s (or 1 min for 1 day’s recording, 10 min for 1 week, 30 min for 1 month or more).
