Fluke 434/PWR Three- Phase Power Analyzer

Description

The Fluke 434/PWR power analyzer is the ideal tool for finding energy waste in commercial and factory buildings and equipment. Electricians, field service engineers and maintenance technicians can use this special edition instrument to conduct energy consumption studies and electrical load analysis, and to perform power quality logging and analysis according to EN 50160. Fluke's 434/PWR is a complete three-phase troubleshooting tool that measures virtually every power system parameter: voltage, current, frequency, power, energy consumption, cos f or power factor, unbalance, and harmonics and inter-harmonics.

Features

Captures events like dips and swells, interruptions and rapid voltage changes, based upon ½ cycle rms values
Unique AutoTrend gives you fast insight into changes over time
With a single push of a button, the unique System Monitor gives you an overview of power system performance. It also checks that incoming power complies to EN50160 limits or to your own custom specifications
Logger:
- Detailed, user-configurable long-term recording gives you the 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
Two groups of four channels: simultaneously measure voltage and current on all three phases and neutral
Auto Scaling:
- Easier trend analysis with automatic scaling of the vertical axis – so you will always view the waveforms on a full display
Meets the stringent 600 V CAT IV, 1000 V CAT III safety standard required for measurements at service entrance
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
