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.
