Fluke 434/PWR power quality analyser

The Fluke 434/PWR power quality analyser is a three-phase troubleshooting tool that measures: voltage, current, frequency, power, energy consumption, cos ϕ or power factor, unbalance and harmonics and inter-harmonics.

It can be used for energy consumption studies and electrical load analysis, and to perform power quality logging and analysis surveys in buildings, equipment and machines.

It 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. It meets 600 V CAT IV, 1000 V CAT III safety standards.

A full-colour display uses industry-standard, user-selectable colour coding to correlate measurements with actual wiring. It logs incoming data with an AutoTrend function that highlights changes of data over time. The data can then be analysed with the included software.

A logging function provides 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).
