Fluke 434/PWR Power Analyzer

The easy way to perform energy consumption studies

Load studies and energy assessments

•

Monitor maximum power demand over user-defined averaging periods

•

Demonstrate the benefit of efficiency improvements with energy

consumption tests

•

Measure harmonic distortion caused by electronic loads

•

Analyze reliability problems by capturing voltage dips and swells from

load switching

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 accord-

ing to EN 50160. Fluke’s 434/PWR is a complete three-phase trouble-

shooting 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.

• 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 cur-

rent 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.

Analyze all parameters on display

Measure and record power (W), VA and

VARs. The Fluke 434/PWR adds the

ability to record energy consumption

Phasor diagram shows voltage and

current unbalance, and helps verify

connections.

The System-Monitor overview screen gives

instant insight into whether the voltage,

harmonics, frequency, and the number of

dips and swells fall outside the set limits.

The full color display allows the use of industry-standard color-coding (user selectable) to

correlate measurements with actual wiring

Logging function allows you to custom-

ize measurement selections and provides

analysis of user-selectable parameters

to find intermittent problems or relate PQ

issues to other phenomena/events.

Fluke Power Log Software

Designed to quickly view recorded data, the built-in Power Log software displays

all recorded parameters on interactive trends. Generate a professional looking

report with the ‘PRINT’ function or copy and paste images into a report document

manually. Customize the report generator to easily create your own formats.

Print reports and view graphics with Power Log software.
