The Fluke 437-II Three-Phase Energy Analyzers offers the best in power quality
analysis and introduce, for the first time ever, the ability to monetarily quantify energy losses.
The new Fluke-437-II helps locate, predict, prevent, and troubleshoot power
quality problems in three-phase and single-phase power distribution systems. Additionally, these models
feature revolutionary power quality and energy measurement functions that help facilities reduce electrical
power consumption, and improve the performance and lifespan of electro-mechanical equipment. Below you
will find brief descriptions of these new features.
The Fluke 437 Series II Power Quality and Energy Analyzer is designed specifically for the defense
and avionics industries. Equipped with all the functionalities of the 435 II including PowerWave,
Power Inverter Efficiency and an Energy Loss Calculator, the 437 II goes one step further by
measuring up to 400 Hz. The ability to measure at a higher frequency is necessary for those
working in submarines, aircrafts, and other transport applications.
Fluke's patented Unified Power Measurement system (UPM) provides the most comprehensive view
of power available, measuring:
- Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000 Power
- Detailed Loss Analysis
- Unbalance Analysis
These UPM calculations are used to quantify the fiscal cost of energy loss caused by power
quality issues. The calculations are computed, along with other facility-specific information,
by an Energy Loss Calculator that ultimately determines how much money a facility loses
due to wasted energy.
Traditionally energy savings are achieved by monitoring and targeting, or in other words, by
finding the major loads in a facility and optimizing their operation. The cost of power quality
could only be quantified in terms of downtime caused by lost production and damage to electrical
equipment. The Unified Power Measurement (UPM) method now goes beyond this to achieve
energy savings by discovering the energy waste caused by power quality issues. Using the
Unified Power Measurement, Fluke's Energy Loss Calculator (see screen shot below) will determine
how much money a facility is losing due to waste energy.
The Fluke 430 Series II analyzers provide three ways to analyze measurements. Cursors and zoom
tools can be used "live' while taking measurements, or "off line" on stored measurement data.
Additionally, the stored measurements can be transferred to a PC with the included software
to perform custom analysis and create reports. Measurement data can also be exported to
common spreadsheet programs. Store hundreds of measurement datasets and screen captures for use
in reports (depending on memory capacity).
Pre-programmed setups and user-friendly screens make power quality testing as simple as you would
expect from Fluke. The high-resolution color screen updates every 200 ms and displays waveforms and
wiring diagrams color coded to industry standards. Handy on-screen wiring diagrams for all commonly
used three-phase and single-phase configurations guide you through connections.
Measure true-rms, peak voltage and current, frequency, dips and swells, transients, interruptions, power and power consumption, peak
demand, harmonics up to the 50th, inter-harmonics, flicker, mains signaling, inrush and unbalance.
Designed to help protect you and your equipment, the Fluke 430 Series II analyzers and accessories
are all certified to meet the stringent standards for use in CAT IV 600 V and CAT III 1000 V
environments such as power connections and outlets throughout a low-voltage power distribution
system.
User-configurable, long-term recording of MIN, MAX and AVG readings for up to 150 parameters on all
4 phases. Enough memory is available to record 600 parameters for over a year with 10 second
resolution, or capture smaller variations with resolution down to 0.25 seconds. The logger function is
quickly accessed by the LOGGER button, the simple step-by-step setup makes capturing your important
measurements as easy as can be.
Every time an event or voltage distortion is detected, the instrument triggers and automatically
stores voltage and current waveforms on all three phases and neutral. The analyzer will also trigger
when a certain current level is exceeded. Hundreds of dips, swells, interruptions and transients can be
captured this way. You can see voltage transients as high as 6 kV and as fast as 5 microseconds.
The MONITOR mode delivers a dashboard display of rms voltage, harmonics, flicker, interruptions, rapid
voltage changes, swells, unbalance, frequency and mains signaling. The dashboard is updated live, showing
compliance of each parameter to EN50160 limits or your own limits. Color-coded bars clearly show which
parameters are inside (pass) or outside (fail) limits. During a monitor session, you can easily drill
down to more detail of any parameter to view and capture its trend for a report.
